Hi, IMHO I think it's possible but for "pure Application Cobol Coding".
What I mean is that Cobol V6 does produce a load module with instructions for the requested ARCHLVL you've set. At runtime, only for called LE routines who accomplish some tasks (eg. SQUARE ROOT or something like this), it's meaningful and maybe hopeful that LE "understands" what HW it's running on and uses the best instructions. Regards. Max.
