Hi,
I am working on enhancement project.
it uses IMS-DC where i find extensive use of '3F' in messages that are thrown to screen. Please let me know its use in programming. example is given below

Code:
    03  W07-SYSTEM-ERROR-MESSAGES.
         05  W07-ERROR-MSG1.
             10  FILLER               PIC X(48)    VALUE
              'NO DATA ENTERED - ENTER DATA OR SPECIAL FUNCTION'.
             10  W07-ERR-END1         PIC X        VALUE X'3F'.

         05  W07-ERROR-MSG2.
             10  FILLER               PIC X(21)    VALUE
             'SPECIAL FUNCTION KEY '.
             10  W07-MSG2-SPEC-FUNC   PIC X        VALUE SPACE.
             10  FILLER               PIC X(24)    VALUE
              ' INVALID WHEN IN INSPECT'.
             10  W07-ERR-END2         PIC X        VALUE X'3F'.


Thanks
Anoop

X'3F'is used to shorten the message sent from the program thus improving performance. It's specially used when the message is fixed length. It's placed at the end of the messages and tells IMS this was the complete message though the received length isn't.
