Subroutines (GTA2)

Subroutines are used to easily "jump" to a set of commands within the script.

Subroutine:

A subroutine is created with the next command:

name:
//code goes here 
RETURN

name	An unique name for the subroutine. Note the : at the end of the name!
RETURN	This closes the subroutine. Every command in the subroutine has to be between the name: and RETURN.

You can script the subroutine where ever you want, even before LEVELSTART!

FORWARD

To activate a subroutine at the start of the game, use this command:

FORWARD name:

The FORWARD must be before LEVELSTART

GOSUB

To jump to the subroutine mid-game, you use the next command:

GOSUB name:

Again, don't forget the : at the end of the name. A GOSUB can be everywhere where you want to jump to the subroutine: inside an IF, a WHILE, etc, as long as it's after LEVELSTART.
