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.

This question is mostly out of idle curiosity ...
I've got a simple routine that is designed to replace any 5250 control characters in a RPG source file with blank.
for p = 1 to %len(%trim(SRCDATA));
if %subst(SRCDATA:p:1) < x'40';
%subst(SRCDATA:p:1) = *blank;
endif;
endfor;
Would there be any performance benefit if I used a pointer to update the field?
D charPtr S *
D char S 1A based(charPtr)
.
.
.
for p = 0 to %len(%trim(SRCDATA));
charPtr = %addr(SRCDATA)+p;
if char < x'40';
char = *blank;
endif;
endfor;
Thanks!
