Thanks Ken,
If you provide *no* second param: myHandler requiredParam Then you get an error trying to *execute* the command because pass-by-reference parameters can't be optional.
That's the issue that will probably make it necessary to change my approach.
Originally, I figured I could just try writing to optionalParam and trap for an error; ut it sounds like the engine won't let me get that far.
I'm glad I asked before scripting what I had in mind.
