Yeah, the 3U 0 integer requires V4R4, I believe.  It's easy enough to
switch to a 5U 0, though.   Here's a new example, I hope it works, my
system does not have the ability to compile all the way back to V4R1.

     H DFTACTGRP(*NO) ACTGRP(*NEW) BNDDIR('QC2LE')

     D toupper         PR             1A
     D   character                    1A   const

     D test1           S             10A
     D x               S             10I 0

     c                   eval      test1 = 'fUnKy 123t'
     c                   for       x = 1 to %len(test1)
     c                   eval      %subst(test1:x:1) =
     c                                   toupper(%subst(test1:x:1))
     c                   endfor

     c                   dsply                   test1
     c                   eval      *inlr = *on
