TVLCT, R, G, B, /GET
will load the RGB triplets into the R,G and B variables, which you can
then write to a file if you want (if you don't want to make a new color
table file), no typing needed (well, some).
You can't load color table 41 from the default file(it's my default file to...), but you can
use modifyct to make a brand new color table file, and use loadct to
read table 41 from that, if you want 1..39 as the default, then copy the 39 color tables
from the old color table to the new one.
Chris.

Typing them in manually!? Is that a typewriter you are using? :-)
Try this:
XPalette ; Get the color tables the way you want them.
TVCLT, r, g, b, /Get ; Get the color table vectors.
ModifyCT, 42, 'mycolors', r, g, b
Cheers,
David

thanks christopher and david, i didn't understand that adding /get to
tvlct would load the present internal color table and fill in the r g
b triplets automatically.
now everything is clear...
ciao
