3. 3 The MASTER That Tells All The Synonym – The Road Map from the data to the Report EMPLOYEE.FOC

4. 4 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, $

5. 5 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. 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

7. 7 The MASTER That Tells All How Will I Get There – SEGMENT Declaration SEGNAME=name, SEGTYPE=, PARENT=, CRFILE=, [CRSEG=,] JOIN_WHERE = where test; [ JOIN_WHERE = where test2;],$ [,$] Special Cases Conditional Cross-References Repeated Groups of Data (SUFFIX=FIX/VSAM) SEGNAME=name, SEGTYPE=, PARENT=, OCCURS=VARIABLE|n|fieldname

10. 10 The MASTER That Tells All What Will I See When I get There? FIELD Declaration FIELD = field_name, [ALIAS= alternate name], USAGE=usage format, ACTUAL = physical format, [INDEX|FIELDTYPE =I,][ACCEPT=tests,] [DEFCENT=default century,YRTHRESH=year threshold,] [[ TITLE = "default_title" [, TITLE_ln="title_for_ln"...]] [[, DESC="default_desc" [, DESC_ln="desc_for_ln"...]], $ 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

11. 11 The MASTER That Tells All What Will I See When I get There? FIELD Declaration ALIAS Alternate Name Relational Data: Column Name from Relational Table ORDER Used within OCCURS=segment Virtual field containing occurrence number

12. 12 The MASTER That Tells All What Will I See When I get There? GROUP Declaration GROUP = field_name, ALIAS= alternate name, USAGE=alpha format, ACTUAL = alpha physical format, [INDEX|FIELDTYPE =I,][ACCEPT=tests,] [[ TITLE = "default_title" [, TITLE_ln="title_for_ln"...]] [[, DESC="default_desc" [, DESC_ln="desc_for_ln"...]], $ GROUP = field_name, ALIAS= alternate name, ELEMENTS = n [INDEX|FIELDTYPE =I,][ACCEPT=tests,] [[ TITLE = "default_title" [, TITLE_ln="title_for_ln"...]] [[, DESC="default_desc" [, DESC_ln="desc_for_ln"...]], $

13. 13 The MASTER That Tells All How Will I Get There – Field Declaration FIELDNAME=EMP_ID, ALIAS=EID, USAGE=A9, $ GROUP=NAME1, ALIAS=NAME1, ELEMENTS=2, $ FIELDNAME=LAST_NAME, ALIAS=LN, USAGE=A15, $ FIELDNAME=FIRST_NAME, ALIAS=FN, USAGE=A10, $ FIELDNAME=HIRE_DATE, ALIAS=HDT, USAGE=I6YMD, $ FIELDNAME=DEPARTMENT, ALIAS=DPT, USAGE=A10, $ FIELDNAME=CURR_SAL, ALIAS=CSAL, USAGE=D12.2M, $ FIELDNAME=CURR_JOBCODE, ALIAS=CJC, USAGE=A3, $ FIELDNAME=ED_HRS, ALIAS=OJT, USAGE=F6.2, $

14. 14 The MASTER That Tells All What Are the Rules of the Road? – DBA Security FIELD = … END DBA=dbavalue,$ USER=password, ACCESS=R|RW|U|W, [RESTRICT=SEGMENT,NAME=segment name not allowed] [RESTRICT=FIELD,NAME=field name not allowed] [RESTRICT=VALUE, NAME=segment level for testing|SYSTEM VALUE=“IF test (TABLE)| VALIDATE test (MODIFY)],$

15. 15 The MASTER That Tells All Can I Limit the ROUTEs - FILTERs FILTER name [WITH fieldname] = true/false boolean expression;,$ FILTER MIS WITH EMPINFO.EMP_ID =DEPARTMENT EQ 'MIS'; $
