Uh, well, I was playing tennis. :-(
I'll update them in a minute or two. :-)

Yeah, something like that. The variable name "sz" would have been left
over from code that used the old-style SIZE function. Without keywords,
SIZE(var) returns an array in which the first element is the number of
dimensions. These days one would use SIZE(var, /N_DIMENSIONS) for the
same purpose.
It looks like you have an old copy of the library, Michael. The copies
currently on David's site no longer have this problem:

I'm not speaking for Mark, but I think that "sz" should be
changed to "ndims". :-)
