and prevents the label from being referenced from outside the body of the
macro definition. This suffix also contains a number that is used as a

The following example defines the macro PRINT, which calls the
printf() function (see printf(3S) in HP-UX Reference). The macro
parameter DATA_ADDR is used to set up the argument to be passed to
printf().
PRINT .MACRO DATA_ADDR
ADDIL L'DATA_ADDR,%dp
.CALL
BL printf,%rp
LDO R'DATA_ADDR(%r1),%arg0
.ENDM
The next example defines the macro STORE. STORE places the contents of
the register REG, the first macro parameter, into the memory address
LOC, the second parameter.
STORE .MACRO REG,LOC
LDIL L'LOC-$global$,%r1
STW REG,R'LOC-$global$(%r1)
.ENDM
