I agree, IDL is sorely missing the concept of an "empty array." In
fact it was one of my "Top IDL requests" in the year 2000 :-)

When I need to manage arrays like lists (and deal with all the cases),
I tend to use my CMINSERT and CMDELETE functions. They more or less
condense the stupid crap-work into an easy-to-read function call. Of
course you sacrifice some performance, but I *tried* to make it
perform as well as I could.
