• Var ID
  
  This is the ID number of the variable to decrease
  
  In the case of "Registers", "Var ID" is the ID of the "Register" whose value should be decreased. The "U" tag may be used to specify a user-defined Register. Otherwise, the ID will refer to a Game Register
  
  In the case of Player Variables, "Var ID" is the ID of the Player Variable for the Player that is "Fetched" to "Reference 2" whose value should be decreased. The capital "A" tag may be used to specify an "Active" variable, the lower-case "a" to specify a user- defined "Active" variable, and the lower-case "c" to specify a user-defined Constant. Otherwise, the ID will refer to one of the Player's required Constants
  
  In the case of Object Variables, "Var ID" is the ID of the Object Variable for the Object that is "Fetched" to "Reference 2" whose value should be decreased. The "E" tag may be used to specify an "Extra" variable. Otherwise, the ID will refer to one of the Object's standard variables
  

• Var ID 1
  
• Var ID 2
  
• Dest Var ID
  
  
  The value of the variable given by "Var ID 2" is subtracted from the value of the variable given by "Var ID 1", and the result is stored in the variable given by "Dest Var ID".
  
  In the case of "Registers", "Var ID" is the ID of the "Register" that should be read/written. The "U" tag may be used to specify a user-defined Register. Otherwise, the ID will refer to a Game Register
  
  In the case of Player Variables, "Var ID" is the ID of the Player Variable that should be read/written. The capital "A" tag may be used to specify an "Active" variable, the lower-case "a" to specify a user- defined "Active" variable, and the lower-case "c" to specify a user-defined Constant. Otherwise, the ID will refer to one of the Player's required Constants
  
  In the case of Object Variables, "Var ID" is the ID of the Object Variable that should be read/written. The "E" tag may be used to specify an "Extra" variable. Otherwise, the ID will refer to one of the Object's standard variables
  
  In the case of a Constant Value, "Var ID" is the actual value to be used in the calculation, rather than any variable ID.
  

• Src Var ID
  
• Dest Var ID
  
  
  The value of the variable given by "Src" is subtracted from the value of the variable given by "Dest", and the result is placed into "Dest"
  
  In the case of "Registers", "Var ID" is the ID of the "Register" that should be read/written. The "U" tag may be used to specify a user-defined Register. Otherwise, the ID will refer to a Game Register
  
  In the case of Player Variables, "Var ID" is the ID of the Player Variable that should be read/written. The capital "A" tag may be used to specify an "Active" variable, the lower-case "a" to specify a user- defined "Active" variable, and the lower-case "c" to specify a user-defined Constant. Otherwise, the ID will refer to one of the Player's required Constants
  
  In the case of Object Variables, "Var ID" is the ID of the Object Variable that should be read/written. The "E" tag may be used to specify an "Extra" variable. Otherwise, the ID will refer to one of the Object's standard variables
  
  In the case of a Constant Value, "Var ID" is the actual value to be used in the calculation, rather than any variable ID.
