) Process will be as follows while the conditional expression 1 is satisfied.
Execution line 2 is continuously executed while the conditional expression 2 is not
; satisfied.
break;
Once the conditional expression 2 is satisfied, the execution goes out of the loop by
break (not executing execution line 2), and execution line 3 is executed.
;
;
)
;
When the conditional expression matches the constant 1, execution line 1 is executed
break;
and the switch execution is terminated by break. Evaluation for constant 2 is not
executed, and the execution moves to execution line 3.
;
break;
;
Script will exit and the next instruction/FB in the user program is executed.
