This is the eigth 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.
The version 0.0.8 marks an important milestone for the PL/I front-end project, because the entire PL/I language can now be parsed using only flex and bison.
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 v0.0.8: - Implemented token based lookahead. - All PL/I Keywords can be used as identifiers. - Reduced number of conflicts in the grammar. - Addapted installation instructions to use the gcc-core-3.5 snapshot - Numerous new testcases has been added. - Simplification of INITIAL attribute.

What is pl1gcc ? The pl1gcc project is an attempt to create a native PL/I compiler using the GNU Compiler Collection. The project is looking for more people to join the development and testing. 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. The next release will focus on integration of syntax from VA PL/I and Multics.
If you do try the compiler on some of your own code, please let us know how it goes.
