All I know is it was an IBM minicomputer, and there was no IT department
running it.

Which assembler. There was everything from BAL on BPS to Assembler (F) on OS.
For DOS and OS, libraries were on DASD; for TOS they were on tape. Nothing
supported COPY from cards.

In the early 1960s disk drive were expensive and small; running from tape was
the norm. By the time IBM shipped S/360, disk was much more affordable. I never

The only change in PGM= is APF.
JOBLIB, STEPLIB and SYSLIB used to be strictly PDS; no PDSE or Unix paths.
For MFT and MVT there were multiple reader procs, and for MVT there was also
the ASB reader.
Load libraries could be on any DASD. I hope everybody used only disk and drum;

In 1980 I worked at a photofinishing plant that used punched cards with an IBM
minicomputer running AS/400. It also used paper tape, but not with the AS/400.
Can anyone guess why? I'll give a hint: it is industry workflow related.

My very first OSes were OS PCP and CP-67 back in 1969, but I did not do any
serious OS/360 coding until around 1975. (I was coding for DOS/360 in the
interim.) My recollection is that PGM= worked then more or less exactly as
it does now. I don't recall about STEPLIB for sure -- I think then it was

How did "EXEC PGM=..." originally work, back when punched cards were used?
I suspect SYSIN, but neither SYSLIB nor STEPLIB.

I have done a LOT of assemblies from trays of cards. In DOS/360, in 1970, when
I did so, COPY libraries were always on disk. This was even before spooling in
DOS, so the assembler literally read from the card reader (well, called an
access method that read card-by-card from the card reader).

How did the assembler originally work, back when punched cards were used? I
don't really know.

A stack of file pointers doesn't work when you're reading the copy files from

On Linux, HLASM uses an interface module which maps the MVS

I cannot comment on the question concerning NOTE, POINT, ftell() and
fseek(),

other languages),
you don't need such file positioning functions, because you can easily

If SYSLIB contains UNIX directories and my program contains
nested COPY instructions, does HLASM use NOTE and POINT
to return to the point of the outer copy member?
I know it took a couple APARs to get this finally working.
Was the fix ini BPAM, or did HLASM resort to ftell() and
fseek()? Or
