Of course that is possible, and it is an option that I am aware of.  It's just 
not as immediately usable as a control-card-only solution would be.

You could also use an E15 and return an 8 when you get past the interesting 
data.

Hi Peter,

If you have IBM File Manager you could do what you need with the Data Set Copy 
(DSC) function and an enhanced processing procedure:

$$FILEM DSC  INPUT=DDIN,
$$FILEM      OUTPUT=DDOUT,
$$FILEM      PROC=*
IF FLDI(1,3,C,'GT',"ABC") THEN
  RETURN STOP IMMEDIATE        /* Stop processing           */
/+

Regards,
Peter Van Dyke
