Extract File

The Extract file is created by the EXTRACT phase and is input to the REPORT phase. It contains reformatted images of the Archive Journal records. The Extract file can be kept as an historical file for future special reporting requirements. The Extract record length was changed in IDMS release 15.0 from 303 to 311.

The extract record has a fixed length of 311 bytes. It contains a 52-byte sort header followed by the extract data. The sort header is defined by the report type for which the extract record is generated. The sort header is also used to sequence the Extract file.

The following are various extract data formats and the report types with which the extracts are associated.

Note: The following abbreviations are used for report type:

ACTV = ACTIVITY

PROG = PROGRAM

CE = CHRONOLOGICAL EVENT
