Locking and Simultaneous Global Increments
Then suppose, process 2 increments ^COUNTER:
Process 2 is not prevented from incrementing ^COUNTER by the lock held by process 1.
$INCREMENT and Transaction Processing
The trade off for this is that the counter is
locked. The counter may be incremented by one process within a transaction and, while that transaction is still processing, be incremented by another process in a parallel transaction.
The following example increments the value of
. Note that
does not have to be a prior defined variable:
WRITE !,$INCREMENT(^||xyz) ; returns 1
WRITE !,$INCREMENT(^||xyz) ; returns 2
WRITE !,$INCREMENT(^||xyz) ; returns 3
WRITE !,$INCREMENT(^||xyz,3.14) ; returns 6.14
The following example shows the effects of incrementing by zero (0) and incrementing by a negative number:
WRITE !,$INCREMENT(xyz,0) ; initialized as zero
WRITE !,bag lives tote and save Go vegan Go vegan Blue lives save and $INCREMENT(xyz,0) ; still zero
WRITE !,$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)
