Example
The following procedure illustrates using the $CHKPINF function.
 * * * TOP OF PROCEDURE * * *
BEGIN
PRINT $CHKPINF(0) WITH ' CURRENT CHECKPOINTING STATUS' AT 25
PRINT $CHKPINF(1) WITH ' NEXT SCHEDULED CHECKPOINT' AT 25
PRINT $CHKPINF(2) WITH ' SECONDS UNTIL NEXT SCHEDULED CHECKPOINT' AT 25
PRINT $CHKPINF(3) WITH ' LAST SUCCESSFUL CHECKPOINT TAKEN' AT 25
PRINT $CHKPINF(4) WITH ' SECONDS SINCE LAST SUCCESSFUL CHECKPOINT' AT 25
PRINT $CHKPINF(5) WITH ' # RECORDS CURRENTLY IN CHKPOINT STREAM' AT 25
PRINT $CHKPINF(6) WITH ' # CHECKPOINTS IN CHKPOINT STREAM' AT 25
PRINT $CHKPINF(7) WITH ' EXTENDED QUIESCE STATUS' AT 25
PRINT $CHKPINF(8) WITH ' MAXIMUM CHECKPOINT RECORDS THAT WERE WRITTEN' AT 25
END
* * * BOTTOM OF PROCEDURE * * *

<var class="product">Model 204</var> displays the following output:
3 CURRENT CHECKPOINTING STATUS

2001/11/19 12:20:00.66 LAST SUCCESSFUL CHECKPOINT TAKEN
950.42 SECONDS SINCE LAST SUCCESSFUL CHECKPOINT
7083 # RECORDS CURRENTLY IN CHKPOINT STREAM
1 # CHECKPOINTS IN CHKPOINT STREAM
