Definition
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:
Example
process first_process() //declaration of the first process
begin
second_process(); //which calls 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
