Haha, I can agree with that! Funny thing with Enterprise COBOL... It "properly" sets the high-order bit on the last parm, but supplies no way to interrogate it! So if "THEFUNCTION" was written in COBOL then you have to invoke it thusly: CALL 'THEFUNCTION' USING MAGIC, INPUT-BUFFER, INPUT-LENGTH, OMITTED, OMITTED RETURNING RC. (The OMITTED keyword simply passes an address of NULL.) Oy!
