PL/I variables with names that are the same as PL/I Keywords
will be interpreted by the PL/I Tooling as keywords and not variables.
This affects functionality like Open Declaration, Hover Info, Syntax
Coloring, and Formatting in the PL/I Editor, and Hover Info and Open
Declaration in the System z® LPEX
Editor.
Work Around: Use variable names that do not match PL/I keyword
names.
