Description:
POKEs asterisk sybols to screen memory directly. base arrays contain direction, segment lengths, starting memory locations, and box type. dynamic arrays contin current location, current direction, segment count, and box type.
The square and the long rectagles are 36 chracters each - the routine draws all three boxes at once, one character at a time.
Comments:
The pattern was intriging - wanted to make something more dynamic than just left to right/top to bottom.
