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]
