Example 2

Another approach is to define a new DMCL with all changes made to the existing segment.

In this case you would not have to modify the DMCL a second time, but more syntax is required for the conversion process, as follows:

CONVERT PAGE IN SEGMENT EMPDEMO TO EMPDEMO DMCL NEWDMCL
   FILE EMPDEMO-FILE INTO EMPDDX,
           INSDEMO-FILE INTO INSDDX,
           ORGDEMO-FILE INTO EMPDDX;

This syntax requires that you give each output file a unique ddname for the run only, because the defined ddnames in the target DMCL are the same as the source DMCL. However, once converted, the old DMCL is discarded, and the new one is renamed and the old one is replaced.

Again, if all three files are not affected, the number of files converted can be reduced by not naming the unaffected files.
