Other Trap Definitions

Note: Traps are the mechanism for programs to access system functions.  Most
           of these traps have known names which are contained in the Tattle.Traps
           file.

Unavailable Traps : This lists those named traps that for various reasons
           are not available on your combination of hardware and software. They are
           listed in the following format:

$Trap Number in Hex = _TrapName

Note:  The [address] listed in the following two formats may either be the
          the original ROM address as shipped by Apple or may represent patches that 
          were made by various INITs, control panels, etc.  

Available Traps (Named): This lists named traps available to your 
           machine in the following format:

$Trap Number in Hex = _TrapName [$Address of trap in hex]

Available Traps (UnNamed): This lists unnamed but active traps on your
          machine in the format following.  Since some traps point to the same
          code, one can compare the addresses to determine which are duplicates.
          Duplicate is really not the correct term as Traps which point to the
          same code are generally variations of the original trap.  For example,
           _SetFilType shows the same address at $A043, $A243, and $A443.
          This occurs because, in the case of this type of trap, the $A243 version
          executes the $A043 command immediately, and the $A443 version
          executes the command asynchronously.  Different kinds of traps (e.g.
          Memory, File, Device, etc.) have similar variations with different meanings.
