Name	Type	Related	MEDia	RECtech	MODel	Description
		Parameters
Mount	Command	SUBpool,	Yes	No	No	Mounts scratches that match
		SCRTCH,				the MEDia. If a SUBpool is
		PRIVAT				supplied, a cartridge that
						matches MEDia within the
						subpool is mounted.
TAPEREQ	Control	Various Job	Yes*	Yes*	Yes*	Processes which use this
	Statement	Criteria				control statement correlate
						the MEDia, MODel, and
						RECtech parameters
						supplied by TAPEREQ to
						their definitions. The
						definition of MEDia is taken
						from either the VOLATTR
						control statement or the
						CDS. RECtech or MODel is
						taken from either
						UNITATTR control
						statements or eligible
						transports. For example, a
						volume has a known MEDia,
						so a transport must be found
						that matches the MEDia.
						RECtech or MODel aid
						transport selection when
						they match the MEDia. If
						MEDia is not supplied for a
						nonspecific request, then
						RECtech or MODel, when
						supplied, aid in defining
						which MEDia and
						subsequent volume is
						selected, provided that there
						are eligible transports with
						the RECtech or MODel
						attribute.
						Sometimes incompatibilities
						occur because of improper
						control statement
						definitions. When this
						happens, messages or
						unexpected results can
						occur.
UNITATTR	Control	N/A	No	No	Yes	The transport model, which
	Statement					implies transport
						capabilities, and network
						information is defined by
						this control statement. Lists
						are used to define a pool of
						transports from which to
						select.
