The PL/1 for GCC version 0.0.2 release is based on the syntax from IBM OS PL/I Version 2.
PL/1 for GCC is released under the GNU Public License; version 2.

The first release consist of a scanner and parser for pl1, and is fully integrated into the standard gcc build system, and a set of test files.

The work has been done to fill up some commute time, but mainly out of fascination with the PL/I programming language.

"Front-end" might be a bit of an overstatement, since only the scanner and parser is called from the gcc program.

This version would not have been possible without the help of the valuable Treelang sample language.

If you want to learn PL/I, you are probably better off waiting a few releases, until the various bugs has been eliminated and the code generation is implemented.
