The question is, what is the copyright status of this code? Has Tektronix (https://www.tek.com/) made any statements about releasing it to the public? I no longer remember the conditions under which we got the PLOT 10 code, and any licensing paperwork has long since gone to recycling. ------------------------------------------------------------------------------- - Nelson H.
