Sorry, I was thinking it was a VSE-L post, so I worded my reply for a
VSE programmer. The effects are the same in both z/OS and z/VSE, but the
where I say "partition", read instead "address spaces", and the GETFIELD
macro will be different in z/OS. Also, I am not sure if the SAC values
are the same.

In simple terms:
ALET is the value you stuff into an access register when you want to
access memory in another address space.
Here is a simplified example:
You use
GETFIELD FIELD=ALET,PART=(R11)
to get the ALET for another partition (PIK is in R11).
You then stuff the ALET into an access register:
SAR R7,R1
You switch into AR mode:
SAC 512
you can now use R7 to access another partition's memory
MVC 0(5,R12),0(R7) COPY DATA TO MY PARTITION
You switch out of AR mode:
SAC 0

Hello all, I was trying to find out what an ALET is. I did a search on
the MVS bookshelf and you can't believe how many times ALET came up
and how many manuals are involved. All I was looking for is what it
is, how to define one, and how to use one. If someone can point me to
the manual that describes the ALET, its uses and how to define one, it
will be appreciated.
Thanks.
