So then the difference is reflected in the called handler function as well,
for the non-directing signature:
RexxObjectPtr RexxEntry nonDirectingCommandHandler(RexxExitContext *context,
RexxStringObject address,
RexxStringObject command)
for the redirecting signature:
RexxObjectPtr RexxEntry reDirectingCommandHandler(RexxExitContext *context,
RexxStringObject address,
RexxStringObject command,
RexxIORedirectorContext *ioContext)
