DW> Okay. Here's today's version. I discovered that Q1
 DW> and Q2 must be integers. Formerly, I thought they
 DW> could also be half-integers, so that their sum and
 DW> difference (D and E) would be integral. However,

just remember that in my definition of Pythagorean Triples, they are whole
numbers... not decimal fractions... i've not tried any of your code because
i don't know if it'll run on what i have available... also, i'd like to see
it write to a text file instead of just to the screen... its been too long
since i looked at BASIC... almost 30 years or so ;)
