Use this general macro to subtract two unsigned doublewords.
Format
- label
- is a symbolic name that can be assigned to the macro statement.
- regpair1
- 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.
- regpair2
- is the even register of an even-odd pair of registers that contain the
second operand (a doubleword value) that will be subtracted from the first
operand in regpair1.
Entry Requirements
None.
Return Conditions
The result of the operation will be contained in regpair1.
The condition code will be set as if an SLR assembler instruction was
used.
Programming Considerations
None.
Examples
