John, all Yes, I was really referring to the mainframe assembler that came with MVS 3.8 which is not HLASM. I believe the MVS 3.8 assembler only supported 24 bit addressing like MVS 3.8. I've never really used Hercules so I'm not certain.
z390 supports 32 bit addressing, and is designed to be HLASM compatible although there are exceptions such as the use of ASCII source files and no support for double byte characters. Don Higgins [email protected] www.don-higgins.net
