GeirS VCCC2023 MEGA65 BASIC 88

Author: Geir Straume
Category: Christmas Challenge
System: MEGA65
Language: BASIC
Len source code: 105 chars (as LIST'ed on screen)
Len exe file:    90 bytes
Len code only:   88 bytes (excl. load address)
Instructions:
Install the Xemu emulator (https://github.lgb.hu/xemu/), drag and drop the code.prg file into it.

Description:
The code displays the shape on the screen by drawing diagonal lines, reversing directions
when edges are reached. For the entire shape to be drawn, some "random" direction changes are
also done.

The code loops forever, drawing the shape over and over. It uses the predefined T@& byte array
in BASIC 65 for direct access to screen memory.
