    sys_font.txt        This documentation
    sys_font.img        The Series3 program that changes the system fonts
    norm.fon            A "Greek" version of the normal font
    bold.fon            A "Greek" version of the bold font
    norm.fsc            Source form of norm.fsc
    bold.fsc            Source form of bold.fsc
    sys$norm.fsc        Source of real Series3 (CP850) normal font
    sys$bold.fsc        Source of real Series3 (CP850) bold font
    wsfcomp.exe         Converts *.fsc to *.fon

Copy the file sys_font.img to an \img\ top-level directory on the Series3.
Rename the file if you like.  Also copy versions of files called bold.fon
and norm.fon to the same directory.  The program sys_font (or as you
renamed it) should appear under the RunImg icon in the System Screen.  (In
case you have Removed this icon previously, re-install it, using Install
Standard).

Run sys_font by pressing ENTER while the highlight is over it in the System
Screen.  Task round different applications to see the effect.

The Series3 can be reset to normal by pressing DELETE while the highlight
is again over sys_font in the System Screen.  Or PSION+X from within
sys_font.

Creating .fon files
-------------------

Use sys$bold.fsc as the starting point for your bold font, and sys$norm.fsc
as the starting point for your normal font.  To start with, just change a
few characters, to see the effect.

You edit the *.fsc files using any standard text editor (eg Brief).

To produce eg test.fon from test.fsc, simply type
    wsfcomp test

You can change the name in the "*name" line (first line in the file) if you
like.  But on no account change the height or descent.

Further, you must leave all the characters from 0 to 31 untouched.

You can change the widths of individual characters, but the widths cannot
exceed 8 in any case.  And any character wider than 6 in the normal font
will be clipped when displayed in monospace style.  Note that these widths
INCLUDE the final row of pixels which is normally always blank.

Serious uses of sys_font
------------------------

The built-in fonts are basically code-page 850.  You may want to
change the characters in the region above 127, for whatever reason. 
Then you can enter these additional characters in ANY application.
(However, when applications which their own fonts, such as the small
font in the Spreadsheet, that part of the display will be unaffected).

Follow the above rules and you should get good results.

Break the above rules and all guarantees are off.

Beware earlier versions of sys_font.img
---------------------------------------

Any earlier copies of sys_font.img that may be in circulation should
be destroyed.
