Dr. Fanning-
You are correct, my original problem was that the READ_ASCII function
didn't like my file name. After I fixed that issue I tried passing the
ascii data to the wv_applet function which controls the wavelet tookit.
Since the previous post Ronn Kling noted that it is an add on package that
I don't believe my department has the license for. No big deal really, what
I am basically interested in is how to plot the data after it's been read
by READ_ASCII? I don't believe I need the toolkit for this but I'm not
experienced enough to be certain. The online help indicates the READ_ASCII
places the data in a structure variable, which I assume does not need to be
defined independently?
Cheers,
Patrick
