FILE-CONTROL

The key word FILE-CONTROL names the FILE-CONTROL paragraph. This key word can appear only once, at the beginning of the FILE-CONTROL paragraph. It must begin in Area A, and be followed by a separator period.

file-control-paragraph

Names the files and associates them with the external data sets.

Must begin in Area B with a SELECT clause. It must end with a separator period. See "FILE-CONTROL Paragraph" in topic 4.2.1.

I-O-CONTROL

The key word I-O-CONTROL names the I-O-CONTROL paragraph.

input-output-control-paragraph

Specifies information needed for efficient transmission of data between the external data set and the COBOL program. The series of entries must end with a separator period. See "I-O-CONTROL Paragraph" in topic 4.2.15.
