The GDG syntax is
//SYSIN DD *
DEFINE GDG(NAME (MYLIB.LIB.TEST) -
LIMIT (10) -
NOEMPTY -
SCRATCH)
/*
LIMIT -This parameter is used to specify the total number
of generations that the GDG may contain.
EMPTY -Specifies tht all existing generations of the GDG
are to be uncataloged whenever the generations of GDG
reached the maximum limit.
NOEMPTY -Specifies that only the oldest generation of the
GDG is to be uncataloged if the limit is reached.
SCRATCH -Specifies that whenever entry of the GDG is
removed from the index, it should be deleted physically and
uncataloged.
NOSCRATCH-Specifies that whenever entry of the GDG is
removed from the index, it should not be physically deleted
and uncataloged.
Note:SCRATCH and NOEMPTY are the default parameters.
