Period Table of IDL Operators I was motivated to make a diagram of IDL's operators by Mark Lentczner's [Periodic Table of the Operators]( in Perl. IDL doesn't have nearly as many operators as Perl, so the IDL Periodic Table is much sparser. I added some operators not listed in the [table of precedence]( in the online help. Order of precedence was determined empirically.

Here's the table along with the code and data to make it: [``]( ([docs](, [``]( ([docs](, and [`operators.xml`]( `MGffXMLSAXOperators` is an example of using IDL's SAX parser (and object-graphics).
