Example:
sets
the
number of accessible open file handles to 20.
LASTDRIVE
I
CifJ
1 LASTDRIVE = drive
Sets
the
last
valid drive designation
that
MS-DOS accepts. This
command is only useful
in
a network environment.
drive is
the
logical drive specification of
the
last
valid drive.
It
is
a letter
in
the
range A to
Z.
Note
that
you
do
not place a
colon
following
the
drive letter. The default value is
E.
At
startup,
MS-DOS recognizes five drive letters, A-E, regard-
less of
the
number of physical drives you have on your system. A
network redirection
must
occur to make any of the extra drives
defined by LASTDRIVE valid.
MS-DOS allocates a
data
structure
for
each drive
you
specify.
Therefore,
do
not specify more
than
necessary.
Example:
lastdrive=m
sets
the
last
drive to Drive
M,
unless
you
have added
an
exter-
nal logical device with the device driver DRIVER.SYS. MS-DOS
now
recognizes Drives A through
M.
(See Appendix
C,
"Installa-
ble Device Drivers,"
for
more information on DRIVER.SYS.)
SHELL

Causes MS-DOS to

processor.
This command is intended
for
system programmers
who
write
their
own top-level command processor.
