Definition
INT Signal ( <INT processID|processType> , <INT signal> )
Allows one process to control another process in a limited number of ways, by sending signals.
Returns
INT - Nothing
Parameters
| INT processID or processType | - The ProcessID of the process or the ProcessType of the type of processes to which the signal is to be sent. | 
| INT signal | - The code of the signal that is to be sent to the target process. | 
Notes
To obtain the processType of a function, the operator "Type" can be used. For a process to send a signal to itself, the local variable id can be used. The parameter <signal> is passed by way of a set of predefined constants which denote the signal which is to be sent. These are listed here.
Example
Signal( get_id(type enemy) , s_kill ); // Kills a process of type enemy
Signal( id , s_kill_tree );            // Kills the process that calls it, and all of its descendants
Signal( Type player , s_freeze );      // Freezes all processes of type player so that they are
                                       //     still displayed, but do not execute any code.
