Ok, no idea where one can see the original code (if public at all). I just
found this:
http://newton.freehostia.com/hp/bas/TREKPT.txt
which uses 'LET' keyword in front of all variable assignments. But it is
probably a modified code, as it uses clean white spaces around all 'for'
keywords as well. [shrug]
