Basically, it means the syntax of your XYOUTS command
is wrong, and that "C" can't be used as a location
variable. Maybe you meant to type this:
if (date eq '25052009') then XYOUTS, 23.67, 46.8, 'C', COLOR=253
Cheers,
David

Don't you mean
if (date eq '25052009') then XYOUTS, 23.67,46.8, 'C', COLOR=253
?

Well, I think I tried this first but got an error, then I tried this
notation. But hey, new day new luck. Now everything works fine. Seems
yesterday was the day of the typo. Had another one that kept me banging
my head against the wall for hours.
Thx.
