Description
The 1985 version, published as type-in in Bit-Let magazine, is 16K only and fully implemented in BASIC. Notably, it uses self-modifying BASIC code, which converts the entered function to BASIC tokens and POKEs it into a BASIC line. (On 64K machines, once the graphic memory is allocated, the BASIC code is moved above $4000, so the POKEs will be ineffective.)

The 1987 64K version uses ML code. It has many options once the function has been drawn:
T Display grid
F Calculate values of the function
N Print
