## How to Use IFTHEN, OVERLAY, WHEN, HIT in DFSORT..

```
//SYSIN     DD     *
INREC  IFTHEN =(WHEN=(10,1,CH,EQ'C'),OVERLAY(10:C'+'),HIT=NEXT),
IFTHEN=(WHEN=(27,1,CH,EQ'C'),OVERLAY(27:C'+'),HIT=NEXT),
and so on
SORT FIELDS=COPY
OUTREC FIELDS=(1,3122)
//
Note: HIT=NEXT, tells that to process next IFTHEN
```
