Batch-Control Event Condition

Purpose

(CA ADS Batch only) Tests the occurrence of runtime events, such as end-of-file or physical input errors, specific to batch input.

The event status is initialized at the beginning of application execution and the outcome of each test is false.

Syntax

►►────┬─┬─ $END-OF-FILE ─┬─┬──────────────────────────────────────────────────►◄
      │ └─ $EOF  ────────┘ │
      └─── $IOERRor ───────┘

Parameters

$END-OF-FILE

Tests whether the most recent input file read operation results in an end-of-file condition.

$IOERRor

Tests whether the most recent input file read operation results in a physical input error.

A physical error on a write operation causes the application to abort.

WHILE NOT $EOF
  REPEAT.
    .
    .
    .
    WRITE TRANSACTION.
  END.
LEAVE APPLICATION.
