The prototype does not match the documentation.  Try pointers to the source
and target strings rather than the above.  The RPG400-L archives have
examples of working code (link at the bottom of every message.)  Search for
'cvtch'.  The FAQ (http://faq.midrange.com) has a description of how to
translate the C prototypes into RPG.
