Table
3-1 lists
the system variables, the address they define, and the type of system variable they are.
Figure
3-1
provides
a
partial
listing
of the subprogram
Mass_stg_init,
which shows the current
configuration of the system variables and their
location.
The balance
of
this
section describes the use of the directory pointer and the
mass storage
unit
specifier
in
this
software, and
should give
some
insight as to the
changes
to the
system variables
required to accommodate different storage media. The descriptions supplied assume that
you
are
familiar with
the
operation of your disc
drive.
Before making any changes, read through the directory
pointer and mass storage unit specifier descriptions
in
this
section and
determine
the
modifications
required.
When
you are ready to perform the modification, go to
PERFORMING THE MODIFICATION,
at
the
end of
this section.

Directory Pointer Description
The
following
describes the use
of
the directory
pointer
in
the test software, Although
Manager_sys$
is
referred
to specifically, the description
also applies to
Dut_dir$.
Manager_sys$
defines the directory pointer
for the
test software. Because
the HP 9133H and 9153A
do not use directories to organize information
on the disc,
the directory pointer,
Manager_sys$,
is
set to the
null
string
in
the program
(i.e.,
Manager_sys$="").
For
a
disc drive
that uses directories
and requires the directory pointer to be defined, change
Manager_sys$
to reflect the label of the
directory
where
the test software
is
stored (for example,
Manager_sys$="/8340TEST/"
or Man¬
ager_sys$="/APPLIC/8340TEST/").
Note that the slashes required
for the directory pointer
are
Included on both ends.
Mass Storage Unit Specifier Description
The
following describes the use
of
the
mass storage
unit specifier
in
the test
software. Although
Msus$
is
referred to specifically, the description also applies to
Dut_msus$.
Msus$
is
the mass storage
unit specifier
that
defines the address for
the test software. When
using an
HP 9133H
set to
one volume and HP-IB address 700 or
an HP
9153A
set to
HP-IB address 700, Msus$
is
set as follows:
Msus$=":,700,0"
This designates drive
0
as the storage location for the test software,
When
using other disc drives or
another address, set Msus$ to
reflect the address of your disc drive.
Two examples
could
be;
Msus$=":REMOTE 21,3"
(when using
a
shared resource
management
system) or
Msus$=":,700,0,0"
(when
using an
HP 9133H set
to
more than one volume).
