Converting DBOMP to CA IDMS/DB › Converting DBOMP Load and Maintenance Programs › DBOMP Commands and Corresponding DML

DBOMP Commands and Corresponding DML

Replacing DBOMP commands with equivalent CA IDMS DML statements is part of program conversion (see the previous list of guidelines for conversion). On the following pages DBOMP commands are shown with their equivalent DML statements (and associated logic, where appropriate). DML statements are shown in this order:

• Assembler
• COBOL
• PL/I

Associated Logic

FIND CALC set owner record; OBTAIN NEXT record (member) within set; check for the end of the set; repeat OBTAIN NEXT and check error status until the end of the set.
