RE: SCAN vs %scan

Have you thought about using the SQL REPLACE function? If 'Abc' is always going to be replaced with 'ABC' in every record maybe it would be faster to use SQL and operate on the records as a set.

Subject: 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 occurences 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.
