Empty arrays? [message #63439]

Hello,

I'm starting to dig into IDL programming, and one thing I've found
particularly annoying is the lack of support for empty arrays. Although
I'm using IDL's OO capabilities, I find that I'm spending a lot of time
testing for return results where an empty array would be much more
suitable.

If I'm building an array that will have zero or more entries, I create
a variable, "insert" a dummy value, go through the code adding entries
based on whatever logic, then pop the top dummy value. But even then I
have to check that more than one entry is there so I dont throw an
error with a

return, a[1:*]

This is very basic functionality. Does anyone have a particularly
elegant... well, I'd say solution, but anything is obviously a
workaround. I don't want to fight the language, but I get the feeling
that IDL's philosophy is "yeah, you do it yourself. I can't be
bothered."

Cheers,

Demitri
