Eric:
Thanks for asking. I used BASIC for accessing ASCII files and analyzing data we would pull from long streams of operant data from psychology experiments (basically long streams of numbers up to about 250,000 per file). No commercially available programs were available because of the niche work being done at a university lab. Frankly, once the 2000s rolled around, people kept telling me to get rid of BASIC and move on to something else. BASIC works so why should I move on? Mathematica, however, seems to do some wonderful things that "could" make some of my programming outputs (graphing) easier to achieve. The problem is, I don't know anyone who uses it and all the discussions of the software seem to be people doing work very unlike myself.
