Ok, that was fast! Thanks!
So here are my comments so far...
Yes, my list was incomplete, I did forget BASR, PC, SVC and BAKR.
(Except that SVC doesn't load a linkage register.) But I do think it
was complete enough.
I'm focusing on the forms of the instructions that actually call
something, so I don't think such things are BASR R12,0 particularly
matter here.
FWIW, I say bazz-em.
I hadn't thought of the word "linkage", but yes, I kinda like it.
I'll probably start using some variation of that.
Or perhaps "linking instructions"?
Thanks,
Dave

In Assembler there are many machine instructions that are suitable
for calling subroutines:
- They go somewhere,
- But they also set a register that can be used to return to the
next following instruction.
These instructions include:
- BAL (Branch and link)
- BALR (Branch and link register)
- BAS (Branch and save)
- JAS (jump and save)
- BRAS (Branch relative and save)
- BRASL (Branch relative and save long)
- BASSM (Branch and save and set mode)
My question is this...
What is the collective name for these instructions?
In a sentence such as "Then you branch and link to a subroutine...",
I tend to say "branch and link",
but I'm always unhappy about that...
- Yes, "branch and link" is an accurate description of you're doing,
- While "branch and save" is a bit opaque.
- However, the phrase "branch and link" is ambiguous and invites
unnecessary quibbling.
So my question is... What would you say?
TIA,
