#AREXX & MFF
I'm puzzled that your external function couldn't be found — REXX: is
searched. What is the actual name of the function file? Keep in mind that
when function names are resolved in file-name space that the file extension
used is that specified by the host. If your file is named foo.rexx and MFF
uses .mffm, then calling it as
call foo args,args,etc.
would search for REXX:foo and REXX:foo.mffm and thereby miss the file.
I'm also puzzled about the quotes — all commands issued from REXX are
evaluated as expressions first, so this would normally strip away the
quotes. You might want to run the macro with TRACE C in effect to see
exactly the command being issued.
