FILE-CONTROL Paragraph
File-Control Entries for Sequential Files
HP COBOL supports two types of sequential disk files:
•
A disk file created as a sequential file (also called an entry-sequenced file on
NonStop systems)
•
An unstructured disk file
Also, a COBOL file defined as sequential can be assigned to a tape file, to a device
such as a terminal or process, or to $RECEIVE. See OPEN and RECEIVE-CONTROL
Paragraph.
In HP COBOL, entry-sequenced disk files can have alternate record keys, whose
values can identify individual records. A file-control entry for a sequential file includes
an ORGANIZATION SEQUENTIAL clause or no ORGANIZATION clause (in which
case the file has sequential organization by default).
