I would have used XLATE.

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!
