The IBM PL/I for Windows compiler generates code that is in many cases
no better than the code generated by the likes of Turbo Pascal V3, and
even the code generated by IBM's Enterprise PL/I compiler for z/OS
leaves a lot to be desired. (Disclaimer, I don't have access to anything
after Enterprise PL/I V3R7, current is V4R2, so things may have improved)
