195. Making the most of VIEW (3)      by Andrew G8YHI
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~
One of the nice things about View is that in common with Wordwise+ the most
used editing commands are available from the function keys, either on their
own or in conjunction with SHIFT or CTRL. But unlike Wordwise Plus there is
no mention in the manual of how to program the function keys yourself and
yet the facility is available, albeit after entering *FX228,1 and by using
the function keys in conjunction with CTRL and SHIFT.

The facility is available from both command and edit mode and so might be
used to insert often used phrases. eg *KEY0 COUNT |M  or *KEY1 Wakefield BBC
Micro User Group|M

The keys can also be programmed to insert View's stored commands, which
means that some quite complex composite commands can be created. To do this
we need to know the Ascii codes for the View function keys and the characters
for the definitions that will produce them. Placing |! before a character
adds 128 to its Ascii value and a '|' before a character reduces its Ascii
value by 64. As an example the View stored command EDIT COMMAND has an Ascii
code of 164 which corresponds to |!$. The |! adds 128 to the Ascii value of
36 for the $ character which adds up to 164.  The codes for all the View
stored commands are set out on the next page.

Try and work out some useful definitions. Here are a few suggestions to get
you started.

*KEY 0 PO Box65 |!$ RJ |M |M Wakefield |!$ RJ |M |M WF2 6YZ |!$ RJ |M|
 ( Inserts address, EDIT COMMAND, Right Justify, Next Line etc)

*KEY 1 ...>.............*.......................*.....< |!4 |M|
 ( Insert ruler details, MARK AS RULER, Next Line )

NOTE:- For 160 (highlight one) the |!  is actually  |! followed by a space.
Not easy to show!
