In an interview in the "Communications of the ACM" (volume 30, number 4, April
1987), two of the original instruction-set architects — Andris Padegs and
Richard Case — weighed in on EDIT and EDIT AND MARK.
The interviewer, Alfred Spector, asked: "Did you ever add instructions to help

Paging? The conventional wisdom has always been to stay within one base
register,
The XPL compiler used multiple base registers.
so for systems with 4K pages that isn't an issue. I tend to use LOCTR so that constants aren't

The original architects were good enough to give us ED/EDMK but failed to
provide UNEDIT.

nope, not z15. s/370 (MVS 3.8J/Hercules).
Thanks for the details, that confirms what I was thinking...

I don't need exhaustive error checking; I suspect some TRT magic will help me

into zeros, PACK, negate if necessary.

"... or am I going to have to scan for the sign characters myself, remove
them, pack the result, and flip the sign if it was negative?
You do have to detect and handle leading plus/minus signs in EBCDIC strings
yourself. PACK won't do it.

Something to think about is whether the possible negative or even positive
sign is lowed on the front or the back of the string. Likewise for commas
and decimal point (or variants of those decorators if you take into account
the locale (eg: France, Quebec etc). I've written routines to scan for suc
I'm getting reacquanted with s/370 assembler after a 40 years hiatus.
I'm working through some examples from my Kacmar book, and need to convert from
a character string to a packed decimal. PACK almost works, except it does not

It works for me with HLASM R6.0, and is as Charles Mills said: it changes the

I wouldn’t think it would change the relative address in the object? Because
then your entry point would be greater than the CSECT size.

I was referring to CP routines calling other CP routines. It's true

In DOS/360 there was only a single address space containing the supervisor
