Scott, to answer your question
>> can I call this routine from LE COBO ? Yes you can- the problem is somewhere else. What I saw at a cursory look--- LTR does not set the overflow cc, so you will always go the BNO path. For the rest- I can only suggest a good debugger- TPF (for z/OS) or mine TRAPPER (for z/VSE) - both will help to quickly resolve the issues with the code. -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
