MyWord=MyByte1 MOD MyByte2
Syntax: Variable = value1 AND value2
Variable: Variable of Byte oder Word type
value1 Variable, value oder constant of Byte oder Word type
value2 Variable, value oder constant of Byte oder Word type
Using ths operators with IF then, they behave like a function call that accepts two parametres and
returns either True or False.

PROGRAM FLOW CONTROL
PAUSE
Holds a program for a specified time
PAUSE is the simplest instruction for flow control. It stets the program for a cerain time on hold. While a
pause is active, system interrupts (e.g. System Timer) are still executed, but the user interrupt INTERRUPT
is executed after pause has ended. The Pause value is 20ms units, i.e PAUSE 50 will cause a 1 second
pause.
Syntax: PAUSE = value1
PAUSE 25
Value1: Variable, value oder constant of
Byte oder Word type.
FOR, TO, NEXT, STEP, EXIT FOR
FOR TO NEXT repeats a group of statements a specified number of times.
Once the loop starts and all statements in the loop have executed, step is added to counter. At this point,
either the statements in the loop execute again (based on the same test that caused the loop to execute
initially), or the loop is exited and execution continues with the statement following the NEXT statement.
The step argument can be either positive or negative. Other as usual the loop is exited at a exact match of
Counter and End only. EXIT FOR will cause an early exit.
You can nest FOR NEXT loops by placing one FOR NEXT loop within another. Give each loop a unique
variable name as its counter.

Counter: Variable used as counter.
Start: Variable, value or constant which is moved to the counter variable as start condition.
End: Variable, value or constant, the counter variable is compared with.
Incr: Required if STEP is used. Term, variable, value or constant defining the increment.
DO, LOOP UNTIL, EXIT DO
Repeats a block of statements while a condition is True or until a condition becomes True.
