DBOMP PL/I Program Preparation and Execution

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

Preparing the PL/I Program

• Remove the PL$BM macro.
• Remove those DBOMP PL/I commands that are not supported by CA IDMS DBOMP Transparency and modify associated program logic as necessary.
• Modify the PL/I 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 program variable storage (see The Transparency Environment):

  call ca$ll (argument_name,'end.')
  

• 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 edits IMBSTAB if a version compatible with the application does not exist in the load library.
• Recompile and link edit the DBOMP PL/I program, including IMBSBRDG, IMBSTAB, IMBSPL1, and CA IDMS/DB. This step assumes that IMBSPL1 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 PL/I program for execution.
