If I understand your question to be, "How can I pass a value back from
a program image to DCL?"  There are several answers:
1)create a logical name or symbol from within the image and set it
to the value you want.
2)use LIB$STOP with it optional status code to pass a value out that with
will be stored in $STATUS and can be checked.  Note that the low 2 bits will
be checked for success, warning, error, severe error!!

If on the otherhand you really want to look at a process register of
another processes space, I do not know how you can do it.

Re     : checking a register from DCL

I have a problem!  Is there a command which will allow
me to determine the value of a register that is returned 
from a foreign process.  

I am running a "C" program and want to check the value 
of register 0 upon returning to DCL program that called
the "C" program.

Any help will be greatly appreciated.
