PL/I for GCC is released under the GNU Public License; version 2.

The current version 0.0.7 marks an important milestone for the project, because the PL/I language can now be parsed using only flex and bison.
See the manual pl1.info for the few exceptions.
If you do try the compiler on some of your own code, please let us know how it went. Mail pl1gcc

• SIGNAL ENDPAGE '(' varnameref ')'

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 or testing. If you want to see a free PL/I compiler please do contact us and join the fun.

Looking ahead.
