You still can!  Prototype it and call it something like GetStrLen.  Internal
to the subprocedure use CHECKR.  Or use an array.  Model it both ways and
see which one you like best!  The point is that with subprocedures you can
extend RPG almost as easily as you can extend CL by writing your own
commands... When you switch to RISC you can either leave your home-grown
function, change the internal of GetStrLen to actually use %LEN or
scan/replace and use %LEN instead of GetStrLen.

Still enthusiastic about subprocedures after 2 years!  Woo Hoo!
