Incrementing and Decrementing a Register

You can add one to or subtract one from the contents of a register using the [ INCR ] and [ INV ] [ INCR ] key sequences.

Increment and Decrement

The RPD-95 app includes specialized forms of data-register addition and subtraction. The [ INCR ] key increments the contents of a register by one, and the key sequence [ INV ] [ INCR ] decrements the contents of a register by one.

Example

The following example demonstrates the use of the INCR function.

Decrement register 000 by one using short-form addressing	[ INV ] [ INCR ] 000
