Heh heh. It's true though - all my routines that use named structures check them on input:

! -- Check that input is, indeed, a structure
Type_Name = SIZE( MyStruct, /TNAME )
IF ( STRUPCASE( Type_Name ) NE 'STRUCT' ) THEN $
MESSAGE, 'Input is not a structure'

! -- Check that it's the right type of structure
Structure_Name = TAG_NAMES( MyStruct, /STRUCTURE_NAME )
IF ( STRUPCASE( Structure_Name ) NE 'MYSTRUCT' ) THEN $
MESSAGE, 'Input is not a MyStruct structure'

But, then, I also do that for longs and floats sometimes too. I'm a belts and braces type
of guy I guess. :o)

To quote Michael from a previous post:

"I believe Java, C and sometimes C++ are the best languages to use when learning how to
design software."

Given that IDL had its beginnings in <shock, gasp> Fortran, maybe that's why he doesn't
grok how IDL handles structures. :o)

p.s. And, yes, I'm just pulling your whizzer Michael. :o)
