I disagree, procedures should not use N_ELEMENTS() to check for
UNDEFINED positional parameters. It should be presumed that the
positional parameters are defined according to the documentation,
anything else should throw an error.

If you want to write a procedure which has more relaxed conditions then
I would recommend using keywords.

Don't most IDL procedures use N_PARAMS() to check for positional
parameters?
This means that there is a difference between calling
READ_PICT, Filename, Image, R, G, B
and
READ_PICT, Filename, Image
regardless of whether R,G,B are defined or not
