The MASTER That Tells All Where Am I Coming From - The FILE Declaration

FILE=filename,SUFFIX=filetype,[FDFC=cent,FYRT=yy,]

[ACCESS=accessfile/DATASET=datasetname],

[REMARKS|DESC=description]

[DESC_ln=description in another language]

FILENAME=employee, SUFFIX=FOC , $

The MASTER That Tells All How Will I Get There – SEGMENT Declaration

• Logical Grouping of Data

• For Relational Data Adapters, will represent different tables, identified in the ACCESS file.

•SEGTYPE - S0 -- no sequence,

Sn -- Sequence is low-to-high within parent

on first n keys

SHn – Sequenced high-to-low within parent

on first n keys

U -- Only 1 child instance per parent

SEGNAME=name, SEGTYPE=, PARENT=, [LOCATION=, [DATASET=,]]

6

The MASTER That Tells All How Will I Get There – SEGMENT Declaration

SEGNAME=name, SEGTYPE=, PARENT=, CRFILE=, [CRSEG=, [CRKEY=,]SEGSUF=suffix [,$]

SEGTYPE: KU Uses Key to access unique instance in CRFILE

KM Uses Key to access multiple instances in CRFILE

KL[U] Uses Linkage in CRFILE to access other segments

CRKEY: Common field in host and cross-referenced file

CRSEG: Name of the segment in its own file/master

SEGSUF: File SUFFIX of cross-reference file (if not equal host) ,$ No field declarations follow

Reserved FIELDNAMES

RECTYPE -- Used for Delimited,FIX,VSAM,IMS files to

indicate different groups of data.

MAPVALUE -- Used within a repeating group to indicate

different groups of data
