Crossfire

SAVE "CROSSFIRE-LINE 1"\nNext type in listing 2 and run it. This pokes in half of the machine code. If the program detects an error it will tell what line it was in. However, it cannot detect certain errors and so it is best to keep a back up copy of it in case the code is wrong. If the program gives a "No errors" message, save the code with SAVE "CODE" CODE 30200,2480\nRepeat this for listing 3 but save the code with SAVE "CODE 2" CODE 30300,2500\nNow clear out the computer with RANDOMIZE USR0 and load both the codes with CLEAR 27899 : LOAD "CODE 1" CODE 27900 : . LOAD "CODE 2" CODE 30380\nThen save the whole code directly after the Crossfire program with SAVE "CODE" CODE 27900,4867
