Interesting note about anonymous structures: p. 7-1 of the IDL User's Manual states: "Anonymous Structures cannot contain other anonymous structures." However... try this: IDL> w = {a: 0, b: 1} IDL> x = {w: w, c: 2} IDL> help, w W STRUCT = -> <Anonymous> Array(1) IDL> help, x X STRUCT = -> <Anonymous> Array(1) IDL> help, x.w <Expression> STRUCT = -> <Anonymous> Array(1) As one of my grade school teachers used to tell us whenever there was an error in a text: "Take out your pencils and cross out that sentence in your textbook." --Wart
