Example 1
By default, if the rule terminates OK, all Database variables are committed. However, if the rule ends NOTOK, statement DO COMMIT=NONE is performed. The variables are not committed because the values extracted from the report in the previous EXECUTE block may be wrong.

Example 2
Total values for the last six months are extracted from a report. Each of these values is saved as a separate generation of the Database variable DB_CURRENCY.TOTAL. This result is achieved by specifying statement DO COMMIT=NOW after each appearance of this variable in the report.
