| After a little break, I am going to try and convert an ASM program of mine to an application. I am aware of the major differences in code. One difference is that an app does not support SMC. I was looking around at different sourcecodes, and I saw some people use SafeRam storage for storing variables. For example, at the top of the program they would define "variablename = SafeRam+1". I have lost the file, however, and I cannot remember the program name. Am I correct in the SafeRam variable idea? How do I use them? |

| I cant. I am using it for a keyhook. But that reminds me, appbackupscreen is actually a variable as well, so I can change the name of appbackupscreen and use it as a var, I believe. Am I correct in saying this? |

No, its an equate for $9872, which happens to be the start of 768 bytes of unused space. |

garbage_1 equ VARS
garbage_2 equ VARS+1
