IMS Data Map Examples

The following examples demonstrate how to create a single-segment data map and a multiple-segment data map by using the example DBD source that PowerExchange provides.

PowerExchange provides the following example DBD source:

DBD   NAME=IMSDEMO,ACCESS=(HDAM,VSAM),X 
      RMNAME=(DFSHDC40,50,80),X 
      EXIT=(*,KEY,PATH,(CASCADE,KEY,PATH),LOG)
DATASET DD1=IMSDEMO,DEVICE=3380,SIZE=8192,SCAN=3
SEGM NAME=IMSDEMOS,BYTES=80FIELD NAME=(DTLKEY,SEQ),BYTES=9,START=3
FIELD NAME=RECTYPE,BYTES=1,START=12FIELD NAME=AMOUNT,BYTES=4,START=13
FIELD NAME=BINNO,BYTES=4,START=17FIELD NAME=DECNO,BYTES=3,START=21
FIELD NAME=DTYY,BYTES=2,START=24FIELD NAME=DTMM,BYTES=2,START=26
FIELD NAME=DTDD,BYTES=2,START=28FIELD NAME=ACCT1,BYTES=10,START=30
FIELD NAME=ACCT2,BYTES=10,START=40
FIELD NAME=ACCT3,BYTES=10,START=50
