The OS/360 materials could not be used as a viable system, but
installations had to generate one to their preferences. And both
the stage 1 and some stage 2 steps required an assembler, so IBM
really didn't have a practical choice. For MVS they provided the XF
assembler free as part of the distribution, and the early high-
level assembler for a charge. I keep wondering whether the
availability of the Waterloo G assembler spurred development of H,
or gave them an excuse to charge?

Good question Gerhard, maybe someone could give us some insight.
Approximately 30-35 years ago we had an application (difficult to
explain) that created "source" (really just huge MF macro's) and the
user designed the system to use only ASM H. In any case 'clerks"
submitted assembler code that were macro's and this generated code
that another program invoked. These "programs" took about 6 minutes
of CPU time to assemble (this was a 168 MP). We kept trying to get
them to change to the G assembler but he wanted to keep the H
compiler. Does anyone remember when H came out and when G came out?
