Thanks David !! It works ! (although I am sure I had the correct number
of frames in a previous try. So, I guess, I must have messed something
up while developing the program - all these unexpected stops; perhaps
XInterAnimate kept on reserving memory but never got a chance to release
it. Who knows. If you'd like to take a look at the result [I managed to
impress some colleagues with the capabilities of IDL], you can download
an mpeg movie from our anonymous ftp site:
ftp io.harvard.edu
cd pub/exchange/mgs
bin
get lpnox1101.mpeg
quit
;-)
