You will need to do a system(9001) to get the program stack
This will tell you the subroutine that is being called.

To get the library, first check the VOC for the external subroutine.  If there 
is no VOC pointer for that item, check the VOC pointer for the calling program.

As far as I remember, when calling a subroutine, UniVerse first checks the VOC 
for the program name to determine the program library where the program 
resides..  If the VOC entry is not present, it uses the library of the calling 
program.  I do not know how far back the stack it will go.. (Hopefully all the 
way to the first program)

Hope that helps.

I just ran a test where a main program called an external subroutine In the 
external subroutine I had it display system(9001)

The subroutine name was listed in that display as was the main routine which 
had called it

I think the point has been lost.
The person is requesting the name of the CURRENT ROUTINE....
If that is A SUBROUTINE - there is no @ that I know of that returns the name of 
the currently executing routine.
The fact the CALLING routine knows the name is #1, is of no value to this 
request and #2, lends nothing to any routine being "self-aware".

I totally agree with and endorse your programming standards David.
However if the program is calling another subroutine it should know the name of 
that subroutine or be able to derive it if it is called with an @.

IT'S JUST NOT TRUE EVER.  @sentence cannot work.

The stub program that launched an initial program will be in the @sentence...
You could be 3 calls deep into external subroutines - there is nothing in 
@sentence re: the call-stack.
Our shop writes *very* few stub programs - most are subroutines called by other 
subroutines.

Instead:
Add
   PGID="programName"
Or even
   PGID="filename  ProgramName"
To the top of the program - quick and easy.
Use of system routines such as SYSTEM(9001) is usually overkill.

Your program should be "aware" of it's name - if no other reasons than:
*  display on the screen to help users identify "where" their problem came from
*  print on reports
*  add to log-file entries
+ and of course, to answer the original question:  "how can I read the
+ current
program source"

A well-designed system/program should hard-code as little as possible as well.
What better key to use for a configuration record than the program name itself.

That's true - if the subroutines are catalogued with a noxref clause you're 
screwed.

You can get the Program name by parsing @SENTANCE You can then read the Verb 
from the VOC and act on that or if the item is globally catalogued then read 
the last line from your catdir item
> From unix level use strings $catpath/$item | tail -1 and then process that.

After all it's not rocket science (pardon the pun) to OPEN "BP" TO BP.FV THEN 
READ R.PROG FROM BP.FV, PROG.ID ELSE ... Whatever END

Does anyone have a BASIC program, that will open it's own code in a variable ?
So something like this

GOSUB RETURN.A.LOCAL.FILE.AND.KEY.FOR.ME

READ THIS.PROGRAM FROM F.LOCALFILENAME, K.PROGRAMKEY ....

the program reads itself.

Does anyone have a program like that?
