I/O

Insbesonders folgender Text:

ILE RPG relies more on data-management error handling than does OPM RPG/400. This means that in some cases you will find certain error messages in the job log of an ILE RPG program, but not an OPM RPG/400 program. Some differences you will notice in error handling are:
  • When doing an UPDATE on a record in a database file that has not been locked by a previous input operation, both ILE RPG and OPM RPG/400 set the status code to "01211". ILE RPG detects this situation when data management issues a CPF501B notify message and places it in the job log.
Mir scheint, du machst keinen Read/Chain mit Satzsperre vorher !
