I think the problem is, that the routine gets in Line 5 without being called. I'd put the do SHOW^PARMS(x,y,.z) before the SHOW label followed by q QUIT.

BTW, when you are in the same routine you don't need "do SHOW^PARMS(x,y,.z)", a "do SHOW(x,y,.z)" works too.

Thank you Jens, for both your replies! I need more coffee before I
implement your advise. :-)
