The CONFIG S Option
This
option
will
let
you
alter
the
system
directly.
With
one
possible
exception, you should not have
to
use
this option.
It
deals
with
elements
of
the
system
that
only a very experienced user should consider, since
the
values
it
changes have been
set
for
optimum
system
performance
under
almost
all
condi tions.
The
one
exception
is
the
CP/M
Version
number
OptiODe
One
of
the
improvements
designed
into
Vector
4 CP/M
deals
with
"locking"
files
and
records
While
in
use.
Although
this
gives
an
added measure of security
to
files in use
by
one
task
or
user, and also allows a slightly
faster
system,
it
is
not
compatible
with
earlier
non-Vector
4
CP/M
versions
(CP/M 2.2,
to
be
specific).
In
order
to
give
Vector
users
the
flexibility
to
use
previously-purchased
applications software, your Vector 4 has the
ability
to
tell
various
programs
that
it
is
either
of
two
versions
of
CP/M: Version 2.5, which is compatible
with earlier
CP/M software; and Version 3.0,
which
takes
advantage
of
file
and
record
lockout
facilities.
If
you
will
be
using
other
Vector
Graphic
software,
be
sure
to
check
the
manual
for
any indication
that
it
is designed
to
run under one or
the
other version of
the
CP/M operating system.
1. Enter CONFIG
S.
The
screen
will display:
DESPOOL TAB EXPANSION (DISABLED):
Enter
[E]
to
enable
the
despool
tab
expansion
at
intervals of eight
characters.
The option is normally
set
for "DISABLED".
Enter
a [RETURN]
to
leave
the
default
(original) value.
2. The screen will display:
DESPOOL CHARACTERS PER
TIME
SLICE (3):
Enter the number of
characters
you
want
to
be
sent
out
during
each
time
slice.
(A
time
slice
is
the
amount of processing time
that
each task or
user
is given in turn.) The normal value is 3
characters
per slice; you
can
specify
a range from 0 through 9.
3.
The
screen
will display:
CCP TO
BDOS
CROSS
BANK
CALLS (DISABLED):
~~~
BDOS
TO
BIOS
CROSS
BANK
CALLS (DISABLED):
IX-20
These
cross
bank
calls
should
be
left
disabled.
They
are
only changeable
because some advanced
programming
functions
may
eventually
need
to
use
l
them.
