You type a prefix command over any of the five equal signs
in the prefix area. You can use either capital or lowercase
letters. Then press the
ENTER key to carry out the
command.
The prefix command that adds a blank line after the one in
which it
is entered is a. You can type a number before or
after the a to add more than one line. The following are all
valid ways to type this command:
====A
a====
IOa==
===A5
Adds one blank line after this line.
Adds one blank line after this line.
Adds ten blank lines after this line.
Adds five blank lines after this line.
There are several prefix commands. Y ou'lliearn some of
them in this section.
If you type a letter that is not one of
these commands and press
ENTER, the prefix area fills up
with question marks and the message line displays
"Invalid
Prefix
Subcommand." To correct the error, you could press
the ERASE
EOF key to clear the prefix area. Then type the
correct prefix command.
Moving through a File
As your files grow, sooner or later they won't fit on one
screen. To look at each screen of the file, you use
commands
that "scroll" the file. Scrolling is like turning the
pages of a book.
Moving Forward or Backward: Two
PF keys are set to
commands that scroll the file. PF8 scrolls forward one
screen.
PF7 scrolls backward one screen.
Moving to the Bottom or Top:
Use the BOTTOM command
to go forward to the end of the file. The
BOTTOM
command makes the last line of the file the new current line.
To move the cursor to the large arrow command line from any
place on the screen, just press the ENTER key.
The TOP command makes the TOP OF FILE line the new
current line. You might want to use this command when you
need
to add a line at the beginning of the file.
