[Coco] [Color Computer] Polymorphisim in BASIC?

[Wes]

In the September '86 issue of the Rainbow there is a 3D graphing program by
Jeff Harper which is polymorphic. The user enters a mathematical function
which is then parsed, tokenized, and POKE'd back into a reserved line
number. The program then calls this line as it draws its graph. Its
tokenizer only handles math functions, but it's still pretty neat.
Definitely worth checking out if you're interested in that sort of thing.
