The Mumps side I understand pretty well. I do
not understand the role of the Remote Procedure file in interfacing to
Delphi/Pascal. Is it just documentation? I assumed it played some
active role in the interface. In the case in question there is only one
input parameter in the formal list on the line tag and that is GRMCO. Y is
of course the return parameter used by remote procedure calls. In this
case the entry in file 8994 says there are two input parameters. Is
it just incorrect documentation? Or can it affect the funtioning of the
interface?

MISMATCH
I don't think I'm quite sure what you are asking. In MUMPS, if
a parameter is not supplied, the corresponding variable is undefined in the
called routine. In cases where the parameters you wish to omit are at the end
of the list, you can simply leave them out
D CALL(X,Y)
but if they are not at the end, you need to supply a "slot" for the
missing parameter as in
D CALL(X,,Z)
Now, if the code being called was something like
CALL(V1,V2,V3) ;
;do stuff
Q
then, in the first case V3 would be undefined, and in the second, V2
would be undefined. Of course, it goes without saying that if the variable
bound to the actual parameter (in this case, X, Y or Z) is undefined, you will
get a run time error.
