Yes, not the same way.

Well, to be sure that this is about compilers, my favorite complaint
is the lost art of small memory compilers.  That is, ones that can
run in kilobytes instead of megabytes.

In any case, the OS/360 compilers don't write out assembly code
that an assembler would recognize.  It is meant for people.

Some write it out in two columns to save paper.
Labels don't have to agree with what assemblers recognize.
They don't have to be in the same order that they would be for
an assembler, though OS/360 object programs don't have to be
in order, either.

Having not thought about this for a while, I believe they put
in some comments that help human readers, though likely not
what an assembly programmer would say.

Unixy systems might put in some comments, but mostly don't.
