What you're doing, as I understand it, is invoking a program from DCL, 
and then exiting the program.  Personally, I find testing the result of 
the program exit, and taking appropriate action, rather elegant.  Guess 
this is a reason some like VMS, and some hate VMS, why some like Unix, 
and some hate Unix.  Different people have different expectations.
