In Universe you can not run a program that is created as an external
subroutine. That is, any program that has the first executable line as:
SUBROUTINE MYPROG(PARAM1, PARAM2)
If you try to run it, directly or indirectly through a catalog entry in
the VOC you get the following message:
"Cannot RUN a subroutine that has arguments."
If the program does not have arguments, THEN you could use the @SENTENCE
variable to see what other command line options were typed in.
