Is there a way to find out what program a user is excuting?

Is there a way to find out what Universe program or lines of code that are being executed by a user via universe or Linux commands?

Gary,
You can use the PORT.STATUS command in the uvhome account and the VLIST command in the account where the program and object code reside.
For example, on a system with no other activity I ran a TEST program as a phantom. Running PORT.STATUS without any argumentes will show all UV processes on the system. The PORT.STATUS will show the object code address if a BASIC program is current running. In the example below, the program is at hex address 0x96.

>PORT.STATUS

There are currently 2 uniVerse sessions; 1 interactive, 1 phantom

Pid.... User name. Who. Port name..... Last command processed............
16187398 root 1 /dev/pts/2 PORT.STATUS
Pid.... User name. Who. Last command processed............................
17760428 root -2 RUN BP TEST [ TEST @ 0x96 ]

When reviewing a specific session, there are other options available. One of them is LAYER.STACK which will show the call stack of the process. In the example below, only the single program is running. If the program was nested due to being called from other programs, the entire call stack would be displayed.

>PORT.STATUS PID 17760428 LAYER.STACK

There are currently 1 uniVerse sessions; 0 interactive, 1 phantom

Pid.... User name. Who. Last command processed............................
17760428 root -2 RUN BP TEST [ TEST @ 0x96 ]

Layer type....... Program name.................... Address...
BASIC run machine TEST 0x00000096

When the source and object code are available, the VLIST command can be used to associated the hex object code address with the relevant line of source code.

That's some great information!  Thanks!  Now if we could just get the debugger to work correctly! LOL
