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.
That is correct, the assembler that comes with MVS 3.8 is the IBM
Assembler XF, and this assembler was also supplied VM and DOS. This is a
complete re-write of the Assembler F which came with MVT. There is also
Assembler "G" which consists of modifications to Assembler F. I am not
sure when Assembler H appeared but thats the pre-cursor to the modern
HLASM.
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.
wasn't HLASM originally Assembler H with the SLAC modification...
