If you search the Google IDL newsgroup archives with
something like "overwrite current line print", you will
probably come up with a couple of methods.
You can also change the text on my progress bar, which
gives the folks something interesting to watch besides
text:
progressbar -> Update, percent, Text='Processing data set 1'
progressbar -> Update, 2*percent, Text='Processing data set 2'
You can find the code here:
htp://www.dfanning.com/programs/progressbar__define.pro
There is an example program at the bottom of the code, so
you can see how it works.
Cheers,
David
