The Change  Display  File 2  command allows  a  change to  one or  more
display  files.   Not  all  of the  CHGDSPF  parameters are  supported.
CHGDSPF2  simplifies making mass changes to  display files.  For a more
complete understanding  of  the  parameters, see  the  CHGDSPF  command
help text.   A  display file owned  by one of  the system  profiles may
not be changed.

You must have *ALLOBJ special authority to use CHGDSPF2.

A typical command would be:

             CHGDSPF2   FILE(ABC/*ALL) WAITFILE(10)

All  display files in library ABC  would be set to a  wait file time of
10  seconds.    All  other   values  in  display  files  would   remain
unchanged.

At  least one  of the  values  to be  changed  must be  other than  the
default of *SAME.
