Note: Both the
Rand
L scroll commands work only if
you have issued the command TERMINAL
WRAP
OFF. See
"TERMINAL"
on
page 7-48 for more
information.
Note: Both the scrolling commands and the
RETRIEVE
command (described below) use an area called the history
buffer.
VM/PC
also uses this buffer when displaying
on
the
screen, such as when you
TYPE a file. Be aware that the
contents of the history buffer may be covered (and lost) by
something displayed
on
the screen.
Retrieving
Commands
You can set a
PF
key
to
RETRIEVE (as we did in the
example in
"PF
Keys Make Work Simpler" on page 5-50).
If
you issue the command
set
pfl0
retrieve
each time you press the
PF
1 0 key
VM/PC
will redisplay the
last command you issued.
Press PFIO again
and
VM/PC
will redisplay the next-to-last, and so on. The commands are
redisplayed
on
the command line and you can reissue them
by simply pressing the
ENTER
key.
You can also change the command before you reissue it. This
can save you a lot
of
typing and time. Try it. Set a
PF
key to
retrieve as shown above, and then press it and watch what
happens.
