Line 1:
This a RYO version of the REXX function '''changestr''' (CHANGE STRing).
It is included in some of the more modern Classic REXXes, but older versions of
<br>Classic REXX don't have this function as a BIF ('''B'''uilt-'''I'''n '''F'''unction).
This version of the '''changestr''' BIF has more functionality than the standard BIF.
