Re: SCAN vs %scan

has anyone benchmarked speed comparison of using SCAN versus %SCAN?

I inherited and am maintaining a fixed-format RPGIV program which
uses SCAN to scan strings for certain values (hundreds of
occurrences of the SCAN opcode), and I am wondering if I can get any
kind of performance improvement if I change them to use %scan
instead.


Perhaps describing more thoroughly what is being accomplished with the hundreds of SCAN operations and using what data structures, might allow for responses suggesting even more alternatives for improvements; i.e. something more than only what might be achieved by using %scan vs SCAN.
