Dropping IDICNF00 parmlib member user exit specifications

Note: Information in this section is applicable to both the Exits and the DumpRegistrationExits options.
It is possible to drop all user exit specifications for a given exit type specified in the IDICNF00 parmlib member by using the special exit name, -DROPCNF-.
If, for example, the IDICNF00 parmlib member contained:
Exits(Control(FRED1,FRED2))
and an IDIOPTS user-options file contained:
Exits(Control(FRED3,-DROPCNF-,FRED4))
then the final logical concatenation of Analysis Control user exits would be:
Type     Name
-------- --------
CONTROL  FRED3
         FRED4
Note that the -DROPCNF- exit name can be specified anywhere that an Exits option can be specified, with the exception of the IDICNF00 parmlib member.
