BB630 OCL

The BB630.ocl36.txt document is an Operation Control Language (OCL) program for an IBM System/36 or AS/400 environment. It is a simple program that serves as a wrapper to execute the BB630 program, likely part of the invoice posting process initiated by BB600P.ocl36.txt. Below is a detailed explanation of the process steps, external programs called, and tables used.

Process Steps of the BB630 OCL Program

The BB630.ocl36.txt OCL program is straightforward and performs the following steps:

  1. Set System Date Handling:

  2. The // GSY2K statement indicates that the program uses Year 2000-compliant date handling, ensuring proper processing of dates in the system (likely for handling two-digit year formats with a century indicator).

  3. Load and Execute Program:

  4. The // LOAD BB630 statement loads the BB630 program into memory for execution.
  5. The // FILE NAME-ARCONT,LABEL-?9?ARCONT,DISP-SHR statement specifies that the ARCONT file (Accounts Receivable control file) is opened with the label ?9?ARCONT (where ?9? is a system prefix, typically the library or environment identifier) and disposition SHR (shared access, allowing multiple processes to read the file concurrently).

  6. The // RUN statement executes the BB630 program.

  7. Program Termination:

  8. After BB630 completes, the OCL program terminates, as there are no further instructions or branching logic.

The OCL program itself does not contain complex logic; its primary role is to set up the environment (file access and date handling) and invoke the BB630 program, which presumably handles specific A/R-related processing, such as updating journal entries or control records after invoice posting.

External Programs Called

  1. BB630:
  2. This is the primary program loaded and executed by the OCL script.
  3. While the exact functionality of BB630 is not specified in the OCL code, it is likely responsible for processing or updating A/R data, given the context of the ARCONT file and its invocation within the invoice posting workflow (related to BB600P.ocl36.txt).

Tables (Files) Used

  1. ARCONT:
  2. Description: Accounts Receivable control file.
  3. Label: ?9?ARCONT (system-generated label with a prefix).
  4. Disposition: SHR (shared access, allowing read-only access by multiple processes).
  5. Purpose: Likely contains control information for A/R processing, such as the next journal number, A/R general ledger number, or last age date, as seen in the BB600P.rpg36.txt program (e.g., ACARJ#, ACSLJ#, ACDATE, ACDTCL).
  6. Usage: Opened for use by the BB630 program, possibly to read or update A/R control data during invoice posting.

Summary

The BB630.ocl36.txt OCL program is a minimal script that: - Configures Year 2000-compliant date handling. - Opens the ARCONT file with shared access. - Loads and runs the BB630 program, which likely performs A/R-related processing as part of the invoice posting workflow.

External Programs Called: BB630. Tables Used: ARCONT.

Since the OCL program is a simple wrapper, the specific functionality depends on the BB630 program, which is not provided but is assumed to interact with the ARCONT file to manage A/R data.
