$I(variable,num)
SET a=7
SET result=$INCREMENT(a)
WRITE !,result /* result is 8 (a+1) */

You can use the

$INCREMENT and Global Variables
-
-
A numeric string ("123" or "+0012.30") is treated as having that numeric value. The string is converted to canonical form: leading and trailing zeros and the plus sign are removed.

-
Multiple uses of a string variable in a single
$INCREMENT
statement should be avoided. For example, avoid concatenating a string variable to the increment of that variable:
strvar_$INCREMENT(strvar)
. This returns unpredictable results.

Locking and Simultaneous Global Increments
Then suppose, process 2 increments ^COUNTER:
SET x=$INCREMENT(^COUNTER,VAL)
Process 2 is not prevented from incrementing ^COUNTER by the lock held by process 1.
$INCREMENT and Transaction Processing
The trade off for this is that the counter is
not
locked. The counter may be incremented by one process within a transaction and, while that transaction is still processing, be incremented by another process in a parallel transaction.
The following example increments the value of
myvar
by
n
. Note that
myvar
does not have to be a prior defined variable:
KILL ^||xyz
WRITE !,$INCREMENT(^||xyz) ; returns 1
WRITE !,$INCREMENT(^||xyz) ; returns 2
WRITE !,$INCREMENT(^||xyz) ; returns 3
WRITE !,$INCREMENT(^||xyz,3.14) ; returns 6.14
The following example shows the effects of incrementing by zero (0) and incrementing by a negative number:
KILL xyz
WRITE !,$INCREMENT(xyz,0) ; initialized as zero
WRITE !,Banquet Clutch Pleats Evening Blue Crystal Bag Womens in Damara $INCREMENT(xyz,0) ; still zero
WRITE !,$INCREMENT(xyz) ; increments by 1 (default)
WRITE !,$INCREMENT(xyz) ; increments by 1 (=2)
WRITE !,$INCREMENT(xyz,-1) ; decrements by -1 (=1)
WRITE !,$INCREMENT(xyz,-1) ; decrements by -1 (=0)
WRITE !,$INCREMENT(xyz,-1) ; decrements by -1 (=-1)
