PL/I for VSE/ESA provides the capability to integrate PL/I applications into Language Environment (LE) for z/VSE®. This integration lets you take advantage of features from both PL/I and LE for z/VSE.
Common function across supported Language Environment-conforming languages and platforms improves usability as well as programmer productivity.
You can use the same source level debugger that is required for the other programming languages in the LE for z/VSE family. One debugger works with all three programming languages.
