Introduction to the CA IDMS DBOMP Transparency › Programming Requirements

Programming Requirements

You must do the following for any DBOMP application program you want to bridge with the transparency:

• Make all database service requests using the following Assembler macros:
  • CA$LL
  • CHA$E
  • GE$T
  • PU$T
  • ST$KY
  • ST$DA

  For PL/I equivalents of these macros, see PL/I Considerations. For COBOL equivalents of these macros, see COBOL Considerations.

• Remove MF$SQ and FI$LE macros from the application program; replace them with the transparency macro IMBSEQ.

  For more information on IMBSEQ, see Transparency Programs and Macros.

• COBOL ConsiderationsUse an index for the logical sequential ordering of master records.

  Note: For more information on indexing, see the CA IDMS Database Administration Guide.

• Make sure that the application program does not combine DBOMP calls with CA IDMS/DB calls.

  For more information on using CA IDMS/DB verbs in a bridged DBOMP program, see How to Include CA IDMS DML Statements.

• Convert any application program that performs structural maintenance functions to CA IDMS/DB.

  For more information on converting maintenance programs, see Converting DBOMP Load and Maintenance Programs.
