COBOL Compiler Validation System (1974) (X3.23-1974) ANS COBOL 1974. Relative I-O Module Test Specifications.

Abstract

The Relative I-O module provides a capability to access records of a mass storage file either random or sequential manner. The 3 access modes RANDOM, SEQUENTIAL and DYNAMIC allow for respective random, sequential and both sequential and random record retrieval. Logical file positioning for accessing the file sequentially is established by the OPEN and START statement. Each record in a relative file is uniquely identified by the value of the relative key for that record. Duplicate key values are therefore not permitted.
