Format
- label
- is a symbolic name that can be assigned to the macro statement.
- regpair
- is the even register of an even-odd pair of registers that contain the
first operand (a doubleword value) and will contain the result of the
arithmetic subtraction.
- storage
- is the label of a storage location that contains the second operand (a
doubleword value) that will be subtracted from the first operand in
regpair.
Entry Requirements
None.
Return Conditions
The result of the operation will be in regpair. The
condition code will be set as if an SL assembler instruction was used.
Programming Considerations
None.
Examples
