As you enter Command Mode commands, 
you will be able to see their effect
in the upper left window.

There are several commands for moving
the cursor:

Z	Move to end of file
B	Move to begin of file

L	Move down one line
10L	Move down 10 lines
-L	Move up one line
-5L	Move up five lines

C	Move right one character
-C	Move left one character
-20C	Move left 20 characters

Type each of these commands.  Remember
to follow each command with a RETURN.

-- Give command "MY" to continue --



Two commands delete text:

D	Delete current character
-5D	Delete previous 5 characters

K	Delete the current line
-2K	Delete the previous two lines

Several commands insert text:

I/text/	Insert the following text
nEI	Insert character with value "n"

For example, give the command:

I/Insert this text. /

To insert the graphics character with
value "205" give the command:

205 EI

-- Give command "MY" to continue --



The real power of Command Mode comes
from the ability to combine commands.

For example, the commands to insert a 
new line at the end of the file are: 
(Note: Press the "<RETURN>" key twice .)

Z I/This is the last line <RETURN>
/ <RETURN>


The commands to delete the first line in 
the file are:

B K


-- Give command "MY" to continue --








The "F" command (Find) searches for
text.  For example, to find the next
occurrence of "the" give the commands:

F/the/

The command to search for the 4th
occurrence of the word "the" is:

4F/the/

The commands to search from the 
beginning of the file for the word "the" 
occurring at the beginning of a line is:

B F/|<the/


-- Give command "MY" to continue --







You can use the Command Mode as a simple 
integer calculator by just typing in the 
algebraic expression you want 
calculated.  For examples, type:

12 + (169 / 13)    (and RETURN)

24 * 92 - 16

You can also calculate the ASCII values 
of characters and control characters.  
For example, type:

"A

Its value is 65 because the letter "A"
is the 65th character of the ASCII 
table.  For the value of <CTRL-S> type:

^S

Its value is 19.
-- Give command "MY" to continue --



The following "macro" will display the 
line numbers of those lines in our file 
which contain the phrase "VEDIT PLUS".  
Type it in carefully.  Note that you 
must press the <ESC> key.

B [ F/VEDIT PLUS/ .Y <ESC> ]

Here is how it works:

The "B" moves to the beginning of the
file.   The "[" and "]" specify a loop
which is to be repeated.  The
"F/VEDIT PLUS/" searches for the phrase.
The ".Y <ESC>" displays the current line
number.  The macro loops until done.

Congratulations.  You have now written
a real computer program!

Here is a macro which counts the number
of words in the file and displays the 
result:

0XS1
B [ F/|S|A/ XA1]
YT/Number of words = / XT1

Try it.  We won't explain how this one 
works.


-- Give command "MY" to continue --












"YI" is a very powerful command which 
lets you re-reroute anything that is 
normally displayed on the screen into 
the file.

For example, try this variation of the
previous macro:

0XS1
B [ F/|S|A/ XA1]
Z
YI YT/Number of words = / XT1


-- Give command "MY" to continue --











This demo has barely scratched the 
capabilities of the Command Mode.
However, we hope that it has given you a 
few hints of how it can be used.

If you are the programming type you may 
want to print the on-line help file
VPHELP.HLP which briefly describes each 
command.
