IDL gurus (and there are many of you!):

it appears that when IDL first starts, !D.N_COLORS and !D.TABLE_SIZE are
both 256 for my 8-bit display, and don't actually report the number of
colors in the shared color table, until a window or device has been
opened. how can i get around this "feature"? i suppose i could open and
close a window before querying these system variables...

also: static color tables are a drag on the mac!!! why won't the
following work on a mac?

loadct,3,ncolors=100,bottom=0
loadct,1,ncolors=100,bottom=100

and how can i implement such a beast on the mac?

by the way, that was a very helpful discussion on IDL variables...much
appreciated!

thanks again,
david mattes
