If all you change in your RPG program is to ADD a HANDLER keyword, is there any way to retain one version of the source?
That is, a way you could run the same source with the same WORKSTN file using and not using a handler?

Two possibilities.

A) Two F-specs and user open based on detecting how you need to run.

Jon, wouldn't you also need to deal with each I/O operation too, to choose which file or record to use?

Fhfile cf e workstn extdesc('FILE')
F rename(scr1:hscr1)
F handler('HDLR')
Ffile cf e workstn usropn
...
if useHandler;
exfmt hscr1;
else;
exfmt scr1;
endif;
