DG Data Types 

The following types of DG data are supported by this COBOL environment:

COMP                  This is identical to COMP in this COBOL system.

DISPLAY               This format obeys the same rules as the DISPLAY
                      format in this COBOL system, except that any
                      processing signs are stored differently.  convert5
                      converts the DG format to the standard ASCII
                      format.  However, if you wish to emulate the DG
                      behavior you can do so by manually amending your
                      source code before you run convert5.  You must
                      change the definition of these fields from signed
                      numeric to alphanumeric.  If you do this you must
                      also set the SIGN directive with the EBCDIC
                      parameter when you submit your code to this COBOL
                      system.

You should note that convert5 does not support the DG INDEX data format.
