That reminds me: PickWiki also mentions the UD program CALL.STACK and a UV program called LAYER.STACK. An old U2 forum post suggests using a command like: PORT.STATUS PID 9 CALL.STACK which for UV might be PORT.STATUS PID 9 LAYER.STACK ? Refs: http://www.mail-archive.com/u2-users%40listserver.u2ug.org/msg173 14.html http://www.pickwiki.com/cgi-bin/wiki.pl?ViewCallStack Does any of that apply to the OP request?

Re: [U2] What Program Am I?
Agreed about use of SYSTEM(9001), however as it is not clear on the platform there is one caveat if you are using UniObjects. You may need to ensure that you are using at least UV 10.2.4 as some previous versions did a hang on consecutive calls to this function (Issue 8283). Am not sure when this bug was introduced so you may be ok.

Re: [U2] What Program Am I?
Regarding debugging phantoms, we've developed an intercept mechanism so when a phantom is triggered from the VB GUI we capture the parameters and return to VB with an error. Then, the programmer can restart the phantom code - but running under a normal session - using an entry point routine that picks up the parameters and launches into the appropriate code. This is great for debugging, and also flagging up non-numerics and unassigned variables - these seem to get missed when the code is only ever run as a phantom.

We've got a UV client/server application with a thick VB client. The vintage is around 1997, and the architecture has a debug mode that I leave on all the time that logs the calls back to the server and the arguments passed back and forth. The server side stuff is all phantomed off, so the output is in the &PH& file. Additionally, you can put display statements in the server side programs and the output from these will be sent to the &PH& record, mingled in with the other stuff. Debugging is old school, as you can't step through programs and any DEBUG statement will halt the server side program with no ability to do interactive I/O, and the client side window will appear hung, requiring the three finger salute. So you spend a lot of time putting in lines of code that look like: DISPLAY "HERE I AM #17" and the like. Eventually I got fed up with counting value marks in &PH& file records and wrote a routine that formats MV data up nicely for display and makes a lot of tedious stuff easier. It makes my life easier.

But there is one thing I'd like to be able to do... It would be super if it were possible to see the call stack from a running program. Kind of like the the UV "T" debugger command. Sometimes I'm just wondering, "How the hell did I get *there*". Or I'll see debugging output in the &PH& file and I wonder, "What program is that from?". In those cases it would be useful to have the call stack sitting beside the output in the &PH& file. Does anybody know a way to do this?

Re: [U2] What Program Am I?
Depending on the version of UV you are on you should be able to access SYSTEM(9001) from memory.

Dave, >From (IIRC) 10.0 onwards, there's the "SYSTEM(9001)" pseudo-variable which contains the UV CALL Stack. It's formatted a bit funny, but there may be a routine on the Pickwiki to make it a sensible format.

[U2] What Program Am I?
We've got a UV client/server application with a thick VB client.
