b) Pausing the display
of
a text file.
When the text
is
displayed
on
the screen, it may be going to fast to be read.
You can pause the display by pressing the
I
PAUSE
I
or
I
CTRL
I -
~
key.
If
you
wish to see some
of
the text which has scrolled out
of
the real screen window,
but
is
still present on the virtual screen, the shifted cursor
keys
(
[!]
and [±] )
can be used when the display has been paused. To continue the display press
any key other than the shifted cursor keys.
c)
Stopping the Display
Pressing any key other
than
the I
PAUSE
I , I
CTRL
I -
~
or
a shifted cursor key
will cause the TYPE command to cease displaying the file. The PX-8 will then
return to show the
CP
1M
prompt.
d) Printing a File using TYPE.
It
is
possible
to
echo the file to the printer by typing I
CTRL
I -
~
before in-
voking the TYPE command, and so produce a hard copy
of
the text.
Small passages (i.e.
of
screen size) can be printed using the screen dump, by
pressing
I
CTRL
I
and
the I
PF5
I key.
e)
Problems with
TYPE
using non ASCII files.
If
an attempt
is
made
to
view a non text file, the screen may be covered with
a garble
of
non
displayable characters. When stopped, the
CP
1M
prompt may
not
appear. In this case you will have
to
press the reset button, and in extreme
cases initialize the system.
See
section 2.1.3
if
this occurs.

USE
R (selecting a different user areas)

USER n
If
more than one person will be using the PX-8 it
is
a good idea to give each
a user number. This has the effect
of
dividing the drives into different areas,
each
of
which contains files belonging to a different user. Thus two users may
label their areas 0
and
1,
and they can both have files with the same names
because their numbers are 'invisibly' added
to
the filenames in their respective
directories. When the PX-8
is
switched on it defaults
to
user area 0, that is,
it assumes you are user number 0 unless you tell it otherwise.
If
you are user
number 2, simply give the command
C>USER
2
and
you will have immediate access to your own files. There must be a space
between USER and the area number.
If
you want to look
at
a file in another
user area you can either give the USER command again with the relevant num-
ber, or use the
PIP
program using the [G) option.
To
find
out
which user numbers are active
on
a particular disk, use the STAT
program.
