PURPOSE:To reduce a burden elating to error processing in a user program by removing the cause of an error in the execution processing part of a data manipulation language (DML) instruction and after that, re-executing the same DML instruction when any error is detected while the DML instruction to be described by the user program is executed and processed. CONSTITUTION:As a result to execute a DML instruction executing means 13, an error detecting means 14 decides whether the error is generated or not and an error recovering means 16 removes the generation cause of the error. After that, an entry load means 17 returns an entry point, which is formerly saved by an entry save mans 11, to an entry save area 41 which is secured in a main storing part 4. Simultaneously, a currency load means 18 returns currently information, which are formerly saved by a current save means 12, to currency save area 42 which is secured in the main storing part 4. Next, a re-executing means 19 delivers control to the entry save means 11. Thus, error processing is easily executed. |
