Thanks Stephan for jumping in.
anArray near the end of the callback function within $.get() now has
the correct values I want from the csv file. I understand what you
said about doing everything from the callback function. But in my case
I have 3 csv files to open and I'd like to perform some graphing
functions (via jQuery plugin flot) after all 3 have been read.
What's unusual (at least to me anyway) is that the global variable
anArray never gets filled with the csv file values outside of the
callback function within $.get(). So I think I must be doing something
wrong.
Thanks again in advance,
Vic
