I was going to suggest declaring the function:

       char *MyProc()

but I just tried it and it doesn't work.  Using this will work:

       MyProc( Str255 myString ) {
	 .
	 .
	 .
	 }

called with:

       Str255 aString;
       .
       .
       .
       MyProc( aString );

This doesn't give you a function, but it may serve your purpose.
