2.10
Repeat Function (Count)
Count
is
displayed on the message line and indicates the
number
of
times
to
repeat a
command.
Some
commands ignore count or, like delete
character
<
DELCH
),
limit
count.
Enter
count before typing a command letter.
It
is
then displayed
at
the left
side
of
the message line. <
RUBOUT)
can
be used to delete
the
vaJue being entered
for count.
The
cursor position
after
a command has been executed count times
is
its
location when count
is
exhausted or no more occurrences are found. When the message
line contains a count, the count is blanked when the next prompt
is
issued.
The
repeat
count
is
an optional decimal repetition factor
in
the range 0 to 65535 (2**]
6-]).
Any
attempt
to type a larger value for count causes AEDIT-86 to beep. A forward slash
(J)
is
accepted as a
count
and
means repeat forever. The default count
is
one.
2.11 Buffer
AEDIT-86
has
three
buffers: the main buffer, the
OTHER
buffer, and the Block
buffer. All three buffers
are
allocated space
in
the user's free
RAM.
The
main buffer
is
the
text area
at
startup. It always contains a portion
of
the main
file.
The
OTHER
buffer
is
accessed with the
OTHER
command and always contains a
portion
of
the
OTH
ER
file
(if
one exists).
The
buffer
that
is
accessed and active
is
referred to as the
"current"
buffer; the one
that
is not being edited, as
the
"secondary"
buffer.
For
example,
if
you are editing a
file
in
the
OTHER
buffer, it would be referred to as the
current
buffer, and the main
buffer would be referred to as the secondary buffer.
If
either
the main or
OTHER
buffer
is
too small for the text file,
AEDIT-86
extends
the
buffer with additional free
RAM
if
it
is
available. When all free
RAM
is
exhausted,
AEDIT-86
writes to temporary files, usually on disk
or
diskette.
AEDIT-
86's
performance improves with the amount
of
free
RAM
available.
The
Block buffer is
the
storage area for text
that
you move, copy,
or
delete, using
the
BLOCK/DELETE
commands.
The
Block buffer allows you to move text between
the
main
and
the
OTHER
file.
The
Block buffer has a fixed size
of
2 Kbytes.
If
more
than
2 Kbytes
is
required,
AEDIT-86
uses a temporary file.
