Hi Folks,
Just want to make aware of a new tool that I stumbled into
writing. But it looks to be more useful than I originally thought. So
I figured to mention it and maybe some people will get mileage out of
it. It is called LISTMOD and it is on File 994 of the Updates page of
www.cbttape.org. You don't need to be APF-authorized to use the tool.
What LISTMOD does, is to display load modules in a readable format,
in an ISPF-like 3-line hex display with ruler. The header gives "some"
useful information to be able to find stuff, but I think that the main
purpose is to make a load module just a bit more accessible and just a
bit more readable, so you can actually STUDY the darn thing. Works for
the more "ordinary" PDSE load modules too, and makes them readable.
Here's an example of the first few lines. The actual display goes
all the way to the end of the load module, beginning to end. If you
want to start from the entry point specified, instead of from the
beginning, use the ENTRY keyword, as in TSO TSOV IEFAB4A0 ENTRY.
Leaving out the ENTRY keyword forces a display of the entire load
module, beginning to end, but the header tells you where to start
looking at the entry point. With or without the ENTRY keyword, you get
the same header information.
The command entered was: TSO (TSOV - to capture and ISPF VIEW the
output) LISTMOD IEFAB4A0
Loaded Program Name: IEFAB4A0

(70817 lines in ISPF. This is a big module.)
A nice thing about this tool is that you don't have to know what
library the load module resides in. You just LISTMOD the name, and the
whole display blaps out in front of you. As I said, it makes load
modules just a little more accessible to look at them. You need a place
to contain the display for large modules, and that's why I included the
"output capturiing tools": TSOB (browse), TSOV (view), TSOE(edit) and
TSOR (REVIEW from CBT File 134, which also works in TSO READY mode), so
you can scroll up and down the (sometimes big) outputs on the screen.
You can also capture a big output file using TSO-in-batch (example
included in File 994).
So to make a load module a little more readable, try this thing
out. It is very easy to use. Please let me know if you like it.
All the best of everything to all of you.
Sincerely, Sam
