[A86] Re: TI 86 Computer Algebra System



Its spagetti code:(   There are entry points and these can be easily
commented (basically have to pass in a few values on that stack) but there
are major differences between the 83 and 86 such as the token issues.  while
programming symbolic, i failed to realize the usefulness of labels instead
of hex values.  so instead of the plus token label, i wrote the hex
values... believe it or not i had most of the tokens memorized at the time.
it is a mess and i'm sorry.  not to mention the dirty hacks i used for
integrating this into the os...
