Automatic structure definition..

[steinhh(at)ulrik.uio.no (Stein Vidar Hagfors Haugan)]

I see that IDL v 5 adds one feature that I've longed for
- automatic structure definition (automatic search for
and execution of a <structure_name>__define procedure
whenever a {<structure_name>} statement is referring
to an as yet undefined structure).

But one question: Why haven't the "builtin" structures
been built in by this method? If I do e.g.:

IDL> help,{widget_draw}
% Attempt to call undefined procedure/function: 'WIDGET_DRAW__DEFINE'.
% Structure type not defined: WIDGET_DRAW.
% Execution halted at:  $MAIN$                 

It would make life so much simpler if RSI were to supply
such routines..... please?
