The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Have you considered coding a faster string search algorithm like Boyer-Moore?

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.
