If the string SEVERE ERROR FOUND, RC= is issued by a program that updates an accounting database, user routine RESTORDB is called by statement DO CALLUSER. This user routine restores the accounting database to its previous state.
The return code from the update program is passed as an argument to the user routine.
EXECUTE block FINISH is executed only if the return code from the user routine is greater than zero.
