Required parameters are ALWAYS positional. Optional parameters MAY be positional.

Is there a way to get around that, other than moving the required
parameter check into the program (and losing the usual consequences of
omitting a required parameter)?


No**. Design your command to work within the Command Analyser structure.


** You could use a Validity Check Program (VCP)to perform this check rather than do it in the Command Processing Program (CPP) but you still won't get the same behaviour as an omitted required parameter would show.
