incr/2 and next/2—return an integer or enumeration slot value incremented by 1
The incr/2
and next/2
operations return an integer or enumeration slot value incremented by 1.
Note
The next/2
function has the same functionality as incr/2
but is used only on enumeration type slots. This function has been deprecated.
incr/2 arguments
Argument | Mode | Type | Description |
---|---|---|---|
| Input | SLOTREF | Specifies an integer or enumeration slot for which the incremented value is to be returned |
| Output | INTEGER|ENUM | Value of the slot incremented by 1 |
Use incr/2
to return the value of the slot referenced in $SLOT
incremented by 1 in the $VAL
argument. For an enumeration, the value of the slot is returned as the next higher value. If there is no higher value, the value of the slot that is returned in $VAL
is not modified.
The referenced slot itself is not modified.
incr/2 example
$NEWPRIO = incr( $E.mc_priority );
