CRUNCHING YOUR SPRITE PROGRAMS

Here's a helpful "crunching" tip: The program described above is already short, but it can be made even shorter by "crunching" it smaller. In our example we list the key sprite settings on separate program lines so you can see what's happening in the program. In actual practice, a good programmer would probably write this program as a TWO LINE PROGRAM... by "crunching" it as follows:

        10 PRINTCHR$(147):V=53248:POKEV+21,1:POKE2040.13:POKEV+39,1           
        20 FORS=832TO894:POKES,255:NEXT:POKEV,24:POKEV+1,100
    
For more tips on how to crunch your programs so they fit in less memory and run more efficiently, see the "crunching guide" on Page 24.
