The PETulant Cursor
|
|
===================
|
|
|
|
This is a tiny (44 bytes long) machine-language demo for the Commodore 64,
|
|
somewhat in the style of later "display hacks" for the Amiga -- surprising
|
|
and silly ways to play with the user interface.
|
|
|
|
So as not to not spoil the fun, try running it before reading the source.
|
|
|
|
To run it, make the file PETULANT.PRG accessible to your favourite Commodore
|
|
64 (or Commodore 64 emulator) in your favourite way, then
|
|
|
|
LOAD "PETULANT.PRG",8,1
|
|
SYS 679
|
|
|
|
For further fun, try changing the text colour (hold the C= or CTRL key while
|
|
pressing a number) or the background colour (POKE 53281 with a number from
|
|
0 to 15) while it is running.
|
|
|
|
I must have originally wrote this sometime in the late 80's. I disassembled
|
|
and rewrote it (to make it play more nicely with existing interrupt handlers)
|
|
in 2008.
|
|
|
|
Who knows -- this could actually be useful, in a ridiculously minor way: it
|
|
makes it much more obvious when control has returned to BASIC immediate mode
|
|
(e.g., when a program has finished loading.)
|
|
|
|
Enjoy!
