DBOMP COBOL Program Preparation and Execution

The guidelines for preparing and executing a DBOMP COBOL program using the transparency parallel those detailed for DBOMP Assembler programs in Using the Transparency as a Bridge to CA IDMS/DB.

Preparing the COBOL Program

• Remove the CB$BM macro.
• Remove DBOMP COBOL commands that are not supported by CA IDMS DBOMP Transparency, and modify associated program logic as necessary.
• Modify the COBOL logic as necessary to conform with CA IDMS DBOMP Transparency specifications for sequential processing and RACN processing.
• If the program issues any of the allowable CA IDMS DML statements, insert the following call to IMBSBRDG, making sure that the CA IDMS DML statement argument is available in working storage (see The Transparency Environment):

  call 'bmpcall' using argument-name.
  

• If any retrieval or update process indicators except for those supported by CA IDMS DBOMP Transparency (see The Transparency Environment) are used in the program, replace them with those that are supported.

Executing the Program

• Assemble and link edit IMBSTAB if a version compatible with the application does not exist in the load library.
• Recompile and link edit the DBOMP COBOL program, including IMBSBRDG, IMBSTAB, IMBSCOBL, and CA IDMS/DB. This step assumes that IMBSCOBL has been assembled and link edited as discussed above.

  Note: You do not need to recompile programs that run under Z/OS unless any of the changes listed above have been made; you must, however, recompile programs that run under Z/VSE whether or not any of these changes have been made, unless the programs exist in the relocatable library.

• Submit the DBOMP COBOL program for execution.
