Priority

Up to Local Variables

Definition

INT priority = 0

priority is a predefined local variable, holding the priority of the process; default is 0.

Using this priority, the order of process-execution can be influenced, because processes with a higher priority are executed before processes with a lower priority.

Example

import "mod_say"
import "mod_proc"
import "mod_timers"

Process A()
Begin
    priority = 0; // Default
    Loop
        say("[" + timer[0] + "] " + "A");
        frame(100000000); // This is very high because Bennu runs without limiter here
    End
End

Process main()
Private
    int f=0;
Begin
    priority = 1; // Set to higher priority than A
    A();
    Repeat
        f++;
        say("[" + timer[0] + "] " + "Main");
        frame(100000000); // This is very high because Bennu runs without limiter here
    Until(f==5)
OnExit
    let_me_alone();
End

Used in example: say(), let_me_alone(), timer, priority, frame

Possible output:

[0] A
[0] Main
[26] Main
[26] A
[50] Main
[50] A
[74] Main
[74] A
[98] Main
[98] A

It can be seen here that regardless of priority, A is first executed, because A is called by Main. As soon as A reaches its frame statement, Main continues until its frame statement and this concludes the first frame. The second frame it is shown that the priority has effect: Main is executed before A.
