PL/I for GCC version 0.0.15 released
September 2007 This is the fifteenth code drop of the GCC front-end for the PL/I programming language. PL/I for GCC is released under the terms of the GNU Public License; version 2. With pl1gcc-0.0.15 the preprocessor do loop, %DO, has been partly implemented. Only one level is allowed. This required quite a bit of restructuring of the internal code. But now it is easy to add more preprocessor statements like %IF and preprocessor %PROCEDUREs. Expect some more releases soon. Further the internal parse tree has also been improved, so code generation should begin really soon now (tm). There is still no code generation taking place, so don't run out and deinstall your production PL/I compiler just yet :-) Changes in v0.0.15 -- * Restructuring parser stack * Improve internal interface to preprocessor * Synchronize with gcc version 4.3 (20070810) * Improved error messages with declares Changed syntax in v0.0.15 - * Non-nested %DO varname = NUM TO NUM * %NOTE can reference preprocessor variables For a complete list of changes check the CHANGELOG file. Source code contributions to pl1gcc --- If you have some PL/I code you do would like to save for the future, then consider to release the source code either under GPL or donate it to the public domain. pl1gcc can offer to host the code for you. What is pl1gcc? --- The pl1gcc project is an attempt to create a native PL/I compiler using the GNU Compiler Collection.

PL/I for GCC version 0.0.14 release
February 2007 This is the fourteenth code drop of the GCC front-end for the PL/I programming language. PL/I for GCC is released under the terms of the GNU Public License; version 2. With pl1gcc-0.0.14 another important milestone has been reached. v0.0.14 is the first release where it is possible to create a partly referencelist for the variables in a program, and an overview of %INCLUDE files. Beside structure level information the referencelist contains the following declare attributes: REAL/COMPLEX FIXED/FLOAT BINARY/DECIMAL AUTOMATIC/BASED/CONTROLLED/DEFINED/STATIC/PARAMETER INTERNAL/EXTERNAL AREA/BIT/CHARACTER/GRAPHIC/PICTURE/WIDECHAR/DATE PROCEDURE/ENTRY There is still no code generation taking place, so don't run out and uninstall your production PL/I compiler just yet :-) Changes in v0.0.14 * added location information to most messages * get rid of warning messages when building pl1gcc * synchronize with gcc version 4.3 Changed syntax in v0.0.14 * allow the tilde(~) character as not operator * allow BUFF as abbreviation for BUFFERS * allow ENVIRONMENT( ... ) as part of OPEN statement * allow %INCLUDE to have filename inside quotes Sourcecode contributions to pl1gcc * From AndyPam Norrie: a project used for score keeping of match-races for halfton yachts.

pl1gcc-0.0.13 released
October 2006 This is the thirteenth code drop of the GCC front-end for the PL/I programming language. PL/I for GCC is released under the terms of the GNU Public License; version 2. Main new feature in pl1gcc-0.0.13 is the preprocessor %GOTO statement. There is still no code generation taking place, so don't run out and uninstall your production PL/I compiler just yet :-) Changes in v0.0.13 * improved internal documentation * many improved diagnostic messages Changed syntax in v0.0.13 * added %GOTO label * added %ACTIVATE variable * added %DEACTIVATE variable * added %NOTE ( level , message ) For a complete list of changes check the CHANGELOG file.

pl1gcc 0.0.12 released
August 2006 This is the twelfth code drop of the GCC front-end for the PL/I programming language. PL/I for GCC is released under the terms of the GNU Public License; version 2. This is mostly a technical release, with some visible user changes. Most notably, the compiler output will now show the compiler options, and a message indicating the number of successfully parsed statements, and further show syntax errors as well. There is still no code generation taking place, so don't run out and uninstall your production PL/I compiler just yet :-) Please inform us about any syntax errors that might occur so we can check if the error is in the pl1gcc parser, and not in your code. Summary of changes in v0.0.12: * Scanner and parser are now reentrant * Synchronized with gcc version 4.2-20060715 * Improved internal documentation of functions * Parsing of procedures and their parameters * Stop compiling at first error * Make compiler output more user friendly Changed syntax in v0.0.12 * Fixed error when %INCLUDE filename was not found * Ignoring hex character 0x1A (ctrl-z, EOF) * Accept but ignore the following preprocessor statements - %SKIP - %PAGE - %PRINT - %NOPRINT Changed semantic checks in v0.0.12: * Error message if procedure name is already defined * Error message if %INCLUDE cannot be resolved * Error message if an unknown character is met * Error messages by bison: Syntax error ...

pl1gcc version 0.0.11 released
May 2006 This is the eleventh code drop of the GCC front-end for the PL/I programming language. PL/I for GCC is released under the terms of the GNU Public License; version 2. Version 0.0.11 includes a new infrastructure for the preprocessor. It has been more than a year since the previous release of pl1gcc, but development has picked up again. And remember you are always welcome to join the project, we need really help at all levels of development. The v0.0.11 release marks another important step forward towards a fully functioning PL/I compiler: the preprocessor. The current implementation supports just a few statement, but thanks to the tools flex and bison, it is straightforward to add the missing preprocessor statements. Expect a few new ones to be added with each new release, just like the PL/I parser has been developed. Currently there is still no code generation taking place, so don't run out and uninstall your production PL/I compiler just yet :-) But read ahead for some good news. It would still be a great help for us if you try the compiler on some of your own source code, or if you could construct a PL/I program that really tests the corners of the grammar. Basically a program that does all what the syntax allows. As inspiration, have a look at the test program written Paul Karagianis http://www.multicians.org/proc-proc.html but I am sure you can create a much worse PL/I program, which we would like to see. And if you release it under GPL it can be added to the pl1gcc hall of fame, so just go ahead and do the coding. Please inform us about any syntax errors that might occur so we can check if the error is in the pl1gcc parser, and not in your code. Changes in v0.0.11: * New preprocessor infrastructure using bison and flex. * Added new compiler option -pp-only: preprocessor scanning only. * Added installation instructions when using Eclipse as development platform. * Added better windows/Cygwin installation instructions, thanks to John Wood. * Refactoring of code to make the code more modular. * Synchronized with gcc version 4.2 Changed syntax in v0.0.11: * Allow DECLARE statements to be empty. * Allow scale for datatype COMPLEX. * Some ENVIRONMENT elements can have a variable as parameter. * Allow subscripts and initial on ALLOCATE statement. * Allow B1 for bit constants * %DECLARE varname FIXED/CHAR * %REPLACE varname BY value * %INCLUDE filename * %INCLUDE environmentvariable ( filename ) For a complete changelog look in the README file.

If you want to help speed up the development of a free PL/I compiler please do contact us and join the fun. Looking ahead. Since two exciting code donations has been done, real code generation is just within reach. A big thank to Patrick and Hugh for releasing their hard work under the GPL license. The contributions are: * Object Oriented Extension generator by Patrick Senti. * PL/I compiler for Windows by Hugh Moran. If you happen to have some PL/I code lying around and you don't know what on earth you should do with it, consider releasing it under the terms of GPLv2, and send it to the pl1gcc project. We will be happy to host the source code for you. Who knows, it might even be possible to see that old code live again once code generation takes place.

I need to figure out how I can augment the generated file to get

In the pl1gcc project, I have implemented token offsets across multiple input

have to code the beancounting yourself.
I had to extend the YYLTYPE structure:
typedef struct pl1ltype

PL/I Frontend for GCC version 0.0.10 released
Cross posted to alt.os.multics comp.lang.pl1 [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] gcc@gcc.gnu.org March 2005 This is the tenth code drop of the GCC front-end for the PL/I programming language. PL/I for GCC is released under the terms of the GNU Public License; version 2. Version 0.0.10 marks yet another milestone for the PL/I front-end project. With this release most if not all of the Multics source code can be parsed using only flex and bison. Special thanks to Tom Van Vleck and Douglas Quebbeman for their effort in providing some 100+ megabytes of Multics source code. It dramatically helped squeeze out many of the quirks of the PL/I grammar. If you have a PL/I project you would like to see supported by the pl1gcc effort, please get in touch with us. If you are testing the PL/I compiler, please inform us about any syntax errors that might occur. It suffers to send the offending line of code. Changes in v0.0.10: * Updated INSTALL to follow gcc.gnu.org/install guidelines * Added new compiler option -isuffix, to control suffix of %include files * Included killer test program from Paul Karagianis www.multicians.org/proc-proc.html * Added offset counting to the location tracking * Enhanced the ./testone script for mass compiling * Added online manual to pl1gcc.sourceforge.net/pl1gcc-0.0.10.doc/doc.html Removed in v0.0.10 * Removed usage of spaces in numeric constants (wrongly introduced in v0.0.9) * Removed compiler option -J, introduced in v0.0.4 Fixed syntax in v0.0.10: * Added 'INITIAL TO' for initialising pointers to strings * Added B2 bitconstants * Allow negative precision and scale for numeric declares * Added attribute expressions to DEFAULT statement * Added RENAME to procedure options * Added support for iSUB array specification * RETURNS on procedure and entry can now specify a structure or array * Added to entry and procedure options - non_quick_blocks, packed_decimal, separate_static, - packed, support, variable,non_quick * Added to environment list - interactive, stringvalue * Added irreducible,reducible to declare statement * Corrected CALL to array of entries with parameters * Added constant,format,local,nonvarying to declare statement * Allow for user defined conditions * Allow '*' in array specifications * Change edit specification for E specifications * On GENERIC declares allow precision range in WHEN option * Allow UNS as abbreviation for UNSIGNED * Allow PARM as abbreviation for PARAMETER * Floating point constants can end with just '.' * Options elements can be separated by blanks or comma * Added 'F' in fixed point constants notation * Ignore various hex codes in scanner For a complete changelog look in the README file.
