Name: Set IWA = -1
Starting Address: &ABDB
Entry criteria: None
Exit: IWA contains -1.
Sets the IWA to -1 [Note: -1 is where every byte of the IWA equals 255], and sets A to #&40 to show that an Integer number is being processed.
Disassembly for the Set IWA = TRUE routine
|ABDB||162 255||A2 FF||LDX#&FF|
|ABDD||...||Store X (#&FF) in every byte of the IWA ... (routine in iFALSE) - ABE8|
