The command analyzer does in fact pass all of the parameters, however it
passes a null pointer for parameters not specified in the command.  Passing
a null pointer is very different than not passing a pointer at
all.  Testing for this is the equivalent of the RPG IV comparison to *NULL,
not the use of %PARMS.

You can pass a null pointer to a CLP program yourself from inside of
another program, but there's no way to do it from a command line.

As already mentioned, CLLE programs play by different rules.
