Function Explanation

The ADR instruction is used to get the address of a variable. Get the variable address and then find
the value stored in the variable address by using the symbol ^.

Programming Example

The ADR instruction is used to get the address of input variable ADR_In and place it in the output
variable ADR1. The address of ADR_In is %MW0. After the ADR instruction is executed, ADR1 points
to %MW0. After ADD is executed, ADR1 points to %MW1. ADR1^ means to get the value from the
address of ADR1. (ADR1 value is %MW1 and ADR1^ means to get the value in %MW1.) The value
in %MW1 is moved to the OUT1 variable through executing MOVE instruction.
