Some older REXXes don't have the '''changestr''' bif, so here is a version: |
|||
<lang rexx>/*──────────────────────────────────CHANGESTR subroutine────────────────*/ |
|||
changestr: procedure; parse arg o,h,n; r=; w=length(o); if w==0 then return n||h |
|||
do forever; parse var h y (o) _ +(w) h; if _=='' then return r||y; r=r||y||n; end</lang> |
