Jim, Since nobody else answered your question about instructions, I thought that I'd give you this reference. It is all that I can find. http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/E0Z2A141/3.1 Basically, to me, it states that Unicode services will run on any processor which will run z/OS. Unicode Services will use the hardware instructions if they exist. So I would guess that the subroutines check the bits in the IHAPSAE (PSA Extention) to determine if the hardware instructions exist on the processor. If so, it uses them, otherwise it uses other instructions. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
