"Variable undefined" error in LOADCT? [message #61444]

Hi IDL Wizards,

This one is interesting. Basically, I'm running a batch graphics
routine making a bunch of plots, and periodically LOADCT gets called,
in this form:

LOADCT,39,/silent

Now, lately this routine will run for a while (several plots) and then
break, with the error:

% Variable is undefined: FILENAME.
% Error occurred at: LOADCT 180

Here is the relevant code from loadct.pro:

if (n_elements(file) GT 0) then filename = file $
else filename = filepath('colors1.tbl', subdir=['resource', 'colors'])
openr,lun, filename, /block

Has anyone ever seen this error?

Ah, good. I was worried about you. :-)

Cheers,
