MAD JUMP 2 for Sinclair ZX-81
by Fredrik Ivarsson
from Your Computer, March 1985

Fredrik Ivarsson leaps into ZX-81 action.


A friend of mine had an Oric program in the September issue of Your
Computer. I have invented a similar game for the ZX-81 16K. You move
Matt on platforms and try to jump up to the top of the screen, but
watch our for the monsters. If you are on the second platform and fall
down to the first platform you will die. You score 10 points every
time you jump and, if you reach the top, 500 points in bonus.

Now, to enter the program, first set RAMtop to 26368 by typing:
	POKE 16389,103
	NEW
Now make a 946 bytes long REM statement by making line 1 to 10 89
characters, then POKE as direct commands:
	POKE 16514,118
	POKE 16515,118
	POKE 16511,178
	POKE 16512,3
	POKE 16510,0

You will now have an empty REM statement. Now enter the hex loader in
listing 1. If you don't want to see line 0 every time you enter a line
you can type:
	LIST 1
	POKE 16419,1

Run the hex loader and type in all the machine code in listing 2. When
that is ready, delete the hex loader and enter the Basic program in
listing 3. When you have done that save the program by typing:
	GOTO 450
