The successor to TSO TEST is ASMIDF. It's still being updated, so can be
considered "modern". While the HLASM Toolkit isn't free, it's so cheap, it
might as well be considered so.

z/OS also includes dbx, described here (z/OS 2.4 link, subject to change,
watch the wrap):

The very first release of OS/390 (generally available on March 29, 1996,
per IBM Announcement Letter 296-018) included an earlier version of dbx,
so dbx will very soon reach a full quarter century of history in the base
operating system. dbx also had a short, earlier history as a separately
chargeable OpenEdition MVS option ("OpenEdition Debugger feature"). Do try
to keep up, please. :-)
According to Wikipedia, dbx's original developer was Mark Linton at the
University of California, Berkeley. He wrote dbx in the period 1981 to
1984, and then it percolated through the BSD ecosystem. TSO TEST first
appeared no later than 1972, so dbx is about a decade younger. Whether dbx
is more "modern" is a separate question. :-)
Another debugger, IBM z/OS Debugger, is the successor to the IBM
Integrated Debugger and IBM Debug Tool. There are lots of IBM software
products that include IBM z/OS Debugger -- 6 if I'm counting correctly --
so it's possible or even likely you already have a license. Of course if
you don't have a license it's possible to acquire one.

Re: Preparing for a short z/OS contract
As others have said, MVS is MVS. However, z/OS has a lot more of posix (Unixy) stuff. TSO TEST is all that comes free with the system. ISPF is still ISPF. REXX may have a few more commands/functions. If they got the debugger (forgot its name) that may help you. I use IPCS and if they have it, zXDC for interactive test of ALC and other stuff.

Re: Preparing for a short z/OS contract
Thanks for the reassurance. Thinking further, I now remember that their only debugger was TSO TEST! I wrote a mixture of Rexx and CLIST commands to extend it a bit (show regs and disassemble the next instruction, every breakpoint). Is there anything more /modern/ that's given away with z/OS? Roops.

Preparing for a short z/OS contract
A client from my contracting days has contacted me out of the blue. Perhaps only a week, but work is work, right? :-) Does anyone have advice they can offer on what to expect these days? When I last worked for them, it was ESA/390, ISPF :-) Does a lot of PL/1, Assembler and Rexx programming work still get done in ISPF, or is it mostly at a *nix terminal? I'm comfortable in Linux, for example, but I've not even seen z/OS running, so I'm unsure about what to expect. Thanks for any advice.
