Remember that SIZE() is an IDL function, so SIZE(0)
evaluates to a 3-element array containing dimension/
data-type info for the value 0.
Just use a different name for your variable.

Very simple. SIZE is an IDL function -- when you just give the name as in
"print, size" it gives the value of the variable but if you subscript it,
it then uses the function SIZE to return info on its argument.
Solution: change the name to (e.g.) SIZ_BAS

I think the problem is that you are using size as a variable to hold the table
size. Since size is also a key word the results you have got are confusing.
Try changing the variable name size to some other name. I tried it, it works.
