Is there a way of accessing the shadow variables for a panel from REXX. There are plenty of references to accessing the actual screen data, but what I'm looking for is something that gives me access to the area in storage that holds the attribute bytes, if there is even something like that.

Other than reading the variable defined on the panel, no there is not. Of course, to read that variable, it means that you must have control of the variable pools; it must be your own application.

If you are trying to capture the editor's shadow variable, there is a diagnostic command HILITE DUMP that creates data set <prefix>.PLEX.DUMP that can be used to get the edit shadow variable in a very round-about way. See http://sillysot.com/ftp/vbcode-generator.zip for an example. Of course, that command is not documented (probably not even known by the current developers for all I know) so it could break at any time

I know about HILITE DUMP and have used your VBCODE stuff in the past, but you also have a wonderful tool called ISPFHTML, and I was hoping that there would be a way to use REXX' "storage" function to get at the data that program is getting at, via z/OS control blocks.

That stuff goes deep into ISPF internals and gets really ugly (and, I'm afraid undocumented and very subject to change). That'd be a can of worms no sane person would want to open without source code and an embarrassingly large amount of free time

I would suggest, as an alternative, that you look at your emulator to see if its screen capture and/or macro language can grab that stuff for you. I think there is a Vista macro out at my site that does that, though I'm sure I haven't looked at (or for) it or tried it in the last decade+ since I went the ISPFHTML route instead.
