Yes. And, because you are using "pass by
reference (or name)", it will work even if Params does not exist. I just
wanted to make sure you that you were not trying to set up Params as multiple
parameters like: SET Paramas="arg1,arg2,arg3". That would require a
different approach.

syntax questions
Maury,
Thanks for your answer. In my code, Params is an array with
multiple possible entries. Will your code still work?
Thanks
You
may think it's ugly, but because M does not support _expression_ indirection,
you have to use the following form:
set
@("OKToCont=$$"_Cmd_"(.Params)")
This assumes that Params is just a
name and not a string of multiple parameters.
M/Mumps supports three
types of indirection: name, argument, and pattern. In a SET command, the
argument is the left side, the equal sign and the right
side.
