INT father

Father is a predefined local variable. Every process has this varaible as soon as the frame; statement is reached within the process. Father holds the ProcessID of the process that called the current process. There are several other local variables which refer to the ProcessID of a related process:

• Son
• Bigbro
• Smallbro

Example

Program example;
Begin
    first_process();
    Loop
        frame;
    End
End

Process first_process()  // Declaration of the first process
Begin
    second_process();  // Call the second process
    Loop
        frame; // This loop makes "first_process()" a process rather than a function
    End
End

Process second_process()  //declaration of another process
Begin
    x = father.x; // These two lines use the father variable to move this process
    y = father.y; // to the position of first_process, as the father variable here
                  // holds the ProcessID of "first_process()"
    Loop
        frame;  
    End
End

Used in example: process, function, processID
