GnuCOBOL https://www.gnu.org/software/gnucobol/ https://sourceforge.net/projects/open-cobol https://savannah.gnu.org/projects/gnucobol GnuCOBOL is a free (like both in 'free speech' and in 'free beer') COBOL compiler, formerly known as OpenCOBOL. It implements a substantial part of the COBOL 85, COBOL 2002 and COBOL 2014 standards, as well as many extensions included in other COBOL compilers. GnuCOBOL translates COBOL into C and compiles the translated code using the native C compiler on various platforms, including Unix/Linux, Mac OS X, and Microsoft Windows. This package contains the following subdirectories: cobc COBOL compiler libcob COBOL run-time library bin COBOL driver program build_aux Helper scripts lib Helper routines for missing OS functionality config Configuration files po International messages doc 'info' and 'pdf' files tests Test suite (GnuCOBOL and framework for COBOL85) extras useful COBOL programs All programs except those in lib and libcob are distributed under the GNU General Public License. See COPYING for details. Programs in lib and libcob are distributed under the GNU Lesser General Public License. See COPYING.LESSER for details. For any copyright year range specified as YYYY-ZZZZ in this package, that the range specifies every single year in that closed interval. Although many have participated, most development thanks go to Roger While Keisuke Nishida See AUTHORS for the author of each file. Requirements *** NOTE For all the following packages (required or optional), BOTH runtime AND development components are necessary. *** *** NOTE All the following packages are normally part of a Linux distribution. Cygwin distribution also has these as installable packages, other operating systems also may have repositories for these - eg. MAC OS, CentOS and others all have package repositories. ALWAYS install the distribution packages when available !! *** GnuCOBOL REQUIRES one of the following external libraries to be installed for implementation of decimal arithmetic: BOTH runtime AND development components required. o GNU MP (libgmp) 4.1.2 or later http://gmplib.org OR o MPIR (libgmp - MPIR gmp-compat) 1.3.1 or later (preferred when compiling on Windows with other compilers than GCC) http://mpir.org GNU MP and MPIR are distributed under GNU Lesser General Public License. NOTE Please ALWAYS use the distro package whenever possible !! See NOTE above. GnuCOBOL MAY require the following external libraries to be installed: *** NOTE - libltdl is NOT needed when installing on Linux, SUN Solaris, MAC OS, CentOS or Windows (including Cygwin, MingW and native windows). It is also NOT needed with later versions of AIX and HP-UX. (AIX >= 5.1 and HP-UX >= 11.1 are known to NOT require this). (Check if you have the 'dlopen' function). *** o GNU Libtool (libltdl) http://www.gnu.org/software/libtool/libtool.html libltdl is used to implement dynamic CALL statements. GNU Libtool is distributed under GNU Lesser General Public License. The following libraries ARE required WHEN : 1) Indexed-Sequential file I/O (ISAM) is used BOTH runtime AND development components required. One of the following: o Berkeley DB (libdb) 4.1 or later http://www.oracle.com/ http://www.oracle.com/technology/products/berkeley-db/db/index.html Berkeley DB is distributed under Oracles own open-source license. Note that if you linked your software with Berkeley DB, you must distribute the source code of your software along with your software, or you have to pay royalty to Oracle. o VBISAM - ISAM file handler (libvbisam) 2.0 or later http://sourceforge.net/projects/vbisam/ VBISAM is distributed under GNU Lesser General Public License. o DISAM File handler (libdisam) http://www.isamcentral.com DISAM is distributed under the proprietary License 'Byte Designs Ltd. DISAM Software License'. 2) SCREEN SECTION and/or extended ACCEPT/DISPLAY is used BOTH runtime AND development components required. One of the following: o Ncurses (ncurses or ncursesw) 5.2 or later http://www.gnu.org/software/ncurses/ncurses.html Ncurses is distributed under a BSD style license. o Unix curses o PDCurses (pdcurses) for MinGW/native windows ports http://pdcurses.sourceforge.net Installation See the INSTALL file for detailed information about how to configure and install GnuCOBOL. Special requirements and further installation notes are listed below. ** NOTE ** The default installation path for GnuCOBOL is /usr/local. The installation path may be changed by specifying --prefix=<dir> as a parameter to the configure. Further parameters may be specified to affect include/library search paths. Execute ./configure --help for further details. To generate/install GnuCOBOL : ************************************** Configure and build ./configure make Here you may run make check to run a series of GnuCOBOL test programs (must do!) This MUST succeed - If not, please report. You may optionally perform a series of COBOL85 tests. make test It is recommended that you perform these tests. ** NOTE ** The language interpreter 'perl' is required to run COBOL85 tests. If you build in Cygwin/MSYS you must use a Cygwin/MSYS version of perl. ** NOTE ** Running 'make test' will try to download the COBOL85 testsuite if it is missing. For details see tests/cobol85/README. If you want to run both tests you can run make checkall Install make install ** NOTE ** You generally need super-user privileges to execute 'make install' unless you changed the installation directory with './configure --prefix=<dir>' and have full access to <dir>. ** NOTE ** On Linux systems, if you are installing for the -first- time, you may need to run 'ldconfig' (as root). In fact, it does not hurt if you always do this. ** NOTE ** On some Red Hat (Fedora) installations and possibly other Linux distros, /usr/local/lib is NOT automatically searched at runtime. Edit /etc/ld.so.conf (or the equivalent file) and add /usr/local/lib to the file. Rerun 'ldconfig'. ************************************** If you think you have a problem or just want to log the output of make, just redirect the output with : make 1>mymake.log 2>&1 make install 1>myinstall.log 2>&1 ************************************** You can get back to a clean installation status by running : make distclean ************************************** The following is only interesting for advanced use. A normal user should not have recourse to use these options. There are many configure options (see configure --help for a full list), these are the most important ones: --with-db Use Berkeley DB >= 4.1 (libdb) (ISAM handler) This is the default --without-db Do neither use Berkeley DB nor any other ISAM handler You will not be able to use indexed I/O --with-vbisam Use VBISAM (libvbisam) (ISAM handler) --with-dl Use the system dynamic linker This is the default --without-dl Use ltdl for dynamic program loading --with-patch-level=<n> Set internal patch level to n (default 0) --with-varseq=<n> Define the default format for variable length sequential files. The default may be overridden at run time by setting the environment variable COB_VARSEQ_FORMAT to 0, 1, 2, or 3. For values of 0, 1 and 2, four bytes are written preceding each record. The format of these four bytes for values of 0, 1, 2 is as follows : n = 0 (default) The first 2 bytes are the record length in big-endian order. This is compatible with mainframe. Bytes 3 and 4 are set to binary 0. n = 1 The 4 bytes are the record length in big-endian order. n = 2 The 4 bytes are the record length in native machine order (int). (This was previously the default) For the value of 3, two bytes are written preceding each record : n = 3 The first 2 bytes are the record length in big-endian order. The record follows immediately after beginning at byte 3. --enable-debug Add '-g' debug option to make Development If you wish to hack the GnuCOBOL source or build from version control, see HACKING. ------------------------------------------------------------------------ NEWS - user visible changes -*- outline -*- GnuCOBOL 3.0rc-1 (20180422) Note: This is a non-feature-complete preview for GnuCOBOL 3.0 There are some known issues in this version but it is considered to be better and more stable than GnuCOBOL 2.2. * New GnuCOBOL features ** REPORTWRITER module added ** INDEXED file support: added support for sparse and split keys ** DISPLAY ... UPON PRINTER may be redirected to an external command (new runtime configuration COB_DISPLAY_PRINT_PIPE) or appended to a file (new runtime configuration COB_DISPLAY_PRINT_FILE, which takes precedence) ** Parser support for many features of different compilers, for example PIC 1 / USAGE BIT, ACUCOBOL extensions for graphical controls VALIDATE statement and much more. Most of them will be fully implemented in a later version... ** Option to dump (partial) data of modules on abort. Use new cobc option -fdump=<scope> to prepare the module and optional use new runtime configuration options COB_DUMP_FILE and COB_DUMP_WIDTH to adjust the dump. ** C interface: new functions cob_set_runtime_option / cob_get_runtime_option to set/get special runtime options (currently FILE * for trace and printer output) or to reload the runtime configuration after changing environment * Changed cobc options: ** The option -debug (runtime checks) no longer implies -ftrace (option to trace program flow of the generated module with COB_SET_TRACE). You may specify -ftrace[all] along -debug if you want to use this feature. ** The option -E (preprocess file) does not imply an output file any more. If no output file is explicit specified with -o filename.i the output will be written to stdout (behavior of versions 1.1 is restored). Requesting output to stdout explicit by using a dash as output name is also possible. ** Changed options for listing: The option -tsymbols was replaced by -ftsymbols and therefore can now also be explicit deactivated by specifying -fno-tsymbols. New options for suppressing (or explicit requesting) parts of the listing: -fno-theader suppress all headers from listing while keeping page breaks -fno-tmessages suppress warning and error summary from listing -fno-tsource suppress actual source from listing (for example to only produce the cross-reference) ** The option -fif-cutoff (option to change generated C sources to use a label + goto for nested if/else) was deactivated to allow the C compiler to fully control the program flow. Please report if you have a need for this option as it will be removed permanently in the next release of GnuCOBOL otherwise. * Changes in the runtime ** updated exception handling, GnuCOBOL now only cleans raised exceptions when requested by SET LAST EXCEPTION TO OFF ** The standard-format for program tracing was changed and is now adjustable by the runtime configuration option COB_TRACE_FORMAT. * New test suite for manual tests (especially SCREEN I/O), run with `make checkmanual`. Note: You may want to adjust the test runner tests/run_prog_manual.sh which defaults to xterm in GUI environments and screen in terminal environments. * New configure option --enable-debug-log to allow internal tracing of GnuCOBOL (intended for developers of GnuCOBOL only) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GnuCOBOL 2.2 released (20170906) * Move to GPL/LGPL 3 * New GnuCOBOL features (too much to list) ** User Defined Functions, FUNCTION-ID. ** New intrinsic functions ABSOLUTE-VALUE alias for ABS CURRENCY-SYMBOL CURRENCY-SYMBOL of the current program FORMATTED-CURRENT-DATE ISO 8601 datetime function FORMATTED-DATE ISO 8601 datetime function FORMATTED-DATETIME ISO 8601 datetime function FORMATTED-TIME ISO 8601 datetime function TEST-FORMATTED-DATETIME ISO 8601 datetime function INTEGER-OF-FORMATTED-DATE date to integer HIGHEST-ALGEBRAIC now implemented LOWEST-ALGEBRAIC now implemented LOCALE-COMPARE now implemented NUMVAL-F now implemented TEST-NUMVAL now implemented TEST-NUMVAL-C now implemented TEST-NUMVAL-F now implemented LENGTH-AN alias for BYTE-LENGTH MODULE-CALLER-ID return the name of the caller MODULE-DATE current module: compilation date MODULE-TIME current module: compilation time MODULE-FORMATTED-DATE current module: formatted datetime MODULE-ID current module: PROGRAM-ID MODULE-PATH current module: path on compile time MODULE-SOURCE current module: name on compile time MONETARY-DECIMAL-POINT LOCALE based fiscal decimal point MONETARY-THOUSANDS-SEPARATOR LOCALE based fiscal visual grouping separator Note: The functions that are actually available as intrinsic functions depend on the -std used. Function names that aren't marked as intrinsic functions by the current -std can be used freely as user defined words or even as user defined functions. ** New system functions C$CALLEDBY return the name of the caller CBL_GC_FORK fork current process (not on Windows) CBL_GC_WAITPID wait for process to end CBL_GC_GETOPT (CBL_OC_GETOPT) comand lineoption parser for COBOL CBL_GC_PRINTABLE (C$PRINTABLE) check if character is printable CBL_GC_HOSTED (CBL_OC_HOSTED) provides access to C extern variables, like stdin, errno CBL_GC_NANOSLEEP CBL_OC_NANOSLEEP CBL_GET_SCR_SIZE get current terminal size - if any CBL_READ_KBD_CHAR get character from terminal CBL_SET_CSR_POS set current position on terminal x'E4' clear terminal screen x'E5' ring the bell ** full support of ANSI 85 debugging module: USE FOR DEBUGGING declarative procedures (only part of the generation if WITH DEBUGGING MODE is active during compilation) and special register: 01 DEBUG-ITEM. 02 DEBUG-LINE PIC X(6). 02 FILLER PIC X VALUE SPACE. 02 DEBUG-NAME PIC X(30). 02 FILLER PIC X VALUE SPACE. 02 DEBUG-SUB-1 PIC S9(4). 02 FILLER PIC X VALUE SPACE 02 DEBUG-SUB-2 PIC S9(4). 02 FILLER PIC X VALUE SPACE. 02 DEBUG-SUB-3 PIC S9(4). 02 FILLER PIC X VALUE SPACE. 02 DEBUG-CONTENTS PIC X(n). With 'n' being at least 30, size is increased if USE FOR DEBUGGING identifier is used and the identifier has a longer size. Note: COB_SET_DEBUG activates the specified debugging sections at runtime ** many new / extended COBOL statements from COBOL2002/2014 and extensions from different COBOL dialects ** more SWITCHes: from SWITCH-01 to SWITCH-36 and its variants from many COBOL dialects ** more IEEE numeric types added, FLOAT-DECIMAL-16, FLOAT-DECIMAL-34, etc ** more literal types added, numeric boolean etc. ** most of the COBOL 2014 spec Compiler Directive Facility is in ** optional: stricter syntax checks ** refactored and extended compiler and runtime messages with available translations (currently to Spanish, Portuguese and Dutch, partial to German) ** screen IO: many extended ACCEPT DISPLAY and SCREEN SECTION changes ** Direct call interface for C: CALL-CONVENTION for CALLs and PROCEDURE DIVISION ENTRY-CONVENTION for PROCEDURE DIVISION and ENTRY statement SIZE of parameters specified for CALL ... BY VALUE RETURN NOTHING for calling void functions RETURN ADDRESS OF VAR for calling functions returning a pointer PROCEDURE DIVISION RETURNING OMITTED -> callable as void function ** Much, much more! * New cobc options: ** New -std options: cobol2014 COBOL 2014 Standard xopen X/Open COBOL Standard mf-strict Micro Focus COBOL compatibility - strict ibm-strict IBM COBOL compatibility - strict ibm-strict MVS/VM COBOL compatibility - strict acu ACUCOBOL-GT compatibility acu-strict ACUCOBOL-GT compatibility - strict bs2000 BS2000 COBOL compatibility (back again) bs2000-strict BS2000 COBOL compatibility - strict rm RM-COBOL compatibility rm-strict RM-COBOL compatibility - strict Note: The GnuCOBOL compiler tries to limit both the feature-set and reserved words to the specified compiler when the 'strict' dialects are used. COBOL sources compiled with these dialects are therefore likely to compile with the specified compiler and vice versa: sources that were compiled on the specified compiler should compile without any issues with GnuCOBOL. With the 'non-strict' dialects GnuCOBOL will activate the complete feature-set where it doesn't directly conflict with the specified dialect, including reserved words and GnuCOBOL specific extensions. COBOL sources compiled with these dialects therefore may work only with GnuCOBOL. COBOL sources may need a change because of rich feature-set and reserved words in GnuCOBOL, otherwise offending words may be removed by `-fno-reserved=word`. COBOL-85, X/Open COBOL, COBOL 2002 and COBOL 2014 are always 'strict'. ** New listing options: -t listing, -T wide listing, --tlines=lines, lines per page of listing -Xref Note: -P, generate preprocessor listing, is still available (and improved) ** All compiler configuration flags may be set on command line to override a specific setting of the current -std, see cobc --help ** All Warnings can be explicit enabled/disabled or even marked as error, see cobc --help -Wunreachable report on possible unreachable statements ** Options for the C compiler/linker: -K <entry>, compile entry point as static (resolve at link time) -A, add options to C compile phase -Q, add options to C link phase ** Miscellaneous -i -info, display build/environment -D define symbol for Compiler Directive Facility -j -job=args, run job after compile input filename of '-' reads source from standard in For more: see cobc --help * New cobcrun options: -i -info, display build/environment -r -runtime-config, display runtime configuration -c -config, set runtime config from file -M -module, set path/module name when looking for entry * New build features make test downloads NIST testsuite if necessary now usable with parallel builds (make -j4 test) make checkall runs both the internal an NIST testsuite ** testsuite defaults to coloured output ** Windows(tm) Visual Studio build support files added, options to validate the software generated with VS against both test suites ** removed maintainer mode - if files need a rebuild because of a change they are always rebuild ** help2man, bison and flex are checked during configure, if they need to be invoked and are missing a useful error message is given ** All files created by GnuCOBOL runtime use the same file permission settings now: COB_FILE_MODE which was changed to 0666 ** changed unix package name from 'gnu-cobol' to 'gnucobol' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GnuCOBOL 1.1 released (20140118) * Change unix package name to gnu-cobol, and project to GnuCOBOL * list of changes see https://open-cobol.sourceforge.io/faq/ #what-are-the-differences-between-opencobol-1-1-and-gnucobol-1-1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ OpenCOBOL 1.1 released (20090206) * Note: was tagged as pre-release and later on as full version ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ OpenCOBOL 1.0 released ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Changes in OpenCOBOL 0.33 * New compile option '-x'. This causes the compiler to produce an executable program. '-fmain' is deprecated. * Remove long option --verbose. Use '-v' for verbosity. Problem is with getopt_long_only which does not like eg. -mv * New conformity option -std=bs2000. * FUNCTION is implemented. See cobc/reserved.c for a list of what is implemented. * Nested programs are partially supported. * LINAGE is implemented. * EXTERNAL on FD is implemented. * SAME RECORD AREA is implemented. * New config variables - 'perform-osvs', 'sticky-linkage'. These are activated for -std=ibm and -std=mvs. 'relax-level-hierarchy'. Allows mismatched data description level numbers. Activated for -std=mf, ibm, mvs and bs2000. * Support for non-gcc compilers. * Large file support, system dynamic loading and Berkeley DB inclusion are default for the configure. ie. ./configure assumes --with-db --with-lfs64 --with-dl * New configure option --with-patch-level=<n> Default is 0. * At run time, version checking is done. ie. When executing/loading Cobol programs, the version (eg. 0.33) and the patch level (eg. 0) are checked against the OC library version/patch level. * Libtool is not required for systems that support native dynamic loading. This includes GNU/Linux, Cygwin and MingW amongst others. * Note to developers : See README for required software versions. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Changes in OpenCOBOL 0.32 * Stability update - See individual ChangeLogs * New internal register - NUMBER-OF-CALL-PARAMETERS * New config variables - larger-redefines-ok, relaxed-syntax-check * Powerpc changes - We now pass all OC and Cobol85 tests ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Changes in OpenCOBOL 0.31 * Stability update - See individual ChangeLogs * New driver program - 'cobcrun' This allows all application programs to be compiled as modules and driven by 'cobcrun' similar to MF's 'cobrun'. Syntax - cobcrun <MAINPROG> [Arguments to program 'MAINPROG'] As 'cobcrun' is linked with the static version of OpenCOBOL libraries, it is easier to maintain concurrent versions on the same system. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Changes in OpenCOBOL 0.30 * Installation changes ** No longer use readline. ** No longer use run-time configuration file (libcob.conf) ** libdb is now optional. Use the new configure option --with-db1 to link with libdb1. Use the new configure option --with-db to link with libdb. Otherwise, libdb will not be linked, and indexed files and SORT/MERGE statements will not work. *** New subdirectory `config' will be installed under $prefix/share/gnucobol. ** Compatibility changes *** New -std options: default used when you omit -std cobol85 COBOL 85 Standard cobol2002 COBOL 2002 Standard ibm IBM COBOL compatibility mf Micro Focus COBOL compatibility v023 OpenCOBOL 0.23 compatibility *** Compile-time options can be stored in a 'config' file. See config/default.conf for details. *** Binary data items are now big endian. The config option `binary-byteorder' controls this. *** Numeric sign of USAGE DISPLAY items has been changed as follows: Positive: 0123456789 Negative: pqrstuvwxy The config option `display-sign' controls this. *** Data items defined in the working-storage section are initialized at the beginning of program by default. The config option `auto-initialize' controls this. *** SORT statement now creates a temporary file in /tmp for sorting and removes it after sorting. ** Feature changes *** COPY statements try to complement the following file extensions: .CBL, .COB, .cbl, or .cob. *** COPY / REPLACE statements are reimplemented for better replacement. *** SPECIAL-NAMES. FORMFEED IS ... *** ALPHABET ... IS EBCDIC. *** EXTERNAL clause. *** SHARING clause. *** USAGE COMP-5 and COMP-X. *** USAGE POINTER and ADDRESS OF operator. *** LENGTH OF operator. *** PROCEDURE DIVISION USING BY REFERENCE/CONTENT/VALUE. *** DISPLAY ... ENVIRONMENT-NAME. ACCEPT ... ENVIRONMENT-VALUE. *** COLLATING SEQUENCE in the SORT and MERGE statements. *** EXIT PERFORM [CYCLE] statement. *** SORT table. *** OPEN ...

Now cobc is the only binary program. ** cobc now generates an executable without `-main' flag. `-main' has been renamed to `-fmain', which is turned on by default if none of -E, -C, -S, -c, or -m is given. ** The default source format is now the fixed form. The format will not be detected automatically. You need to use SOURCE FORMAT compiler directive as described below. This conforms to the COBOL 2002 standard. ** Compiler directive 'SOURCE FORMAT' is now supported. Put the following line at the beginning of file if you want to use the free-form: >>SOURCE FORMAT IS FREE ** Option `-semi-fixed' has been removed.
