<H2>USAGE</H2>
You can run GR0 without any parameters to see available options. They are:
<DL>
<DT><TT>/a</TT>
<DD>Set Atari scheme. It is equivalent to options <TT>/b:1 /c:7 /n /l /x</TT><P>
<DT><TT>/b:nn</TT>
<DD>Set background color nn, where nn is decimal number of range 0-15<P>
<DT><TT>/c:nn</TT>
<DD>Set foreground (letters) color nn, where nn is decimal number of range 0-15<P>
<DT><TT>/d</TT>
<DD>Set default PC font. Resets all characters.<P>
<DT><TT>/f:fname</TT>
<DD>Set external Atari font. Reads characters 0-127 from standard Atari font file
(8*8*128). In 25 lines mode, font is resized. Default extension .FNT will be added
to filename, if none given.<P>
<DT><TT>/i</TT>
<DD>Set characters 128-255 to inverse of 0-127.
<TT>/i</TT> can only be used with <TT>/a</TT>, <TT>/f</TT> or <TT>/x</TT>.<P>
<DT><TT>/l</TT>
<DD>Select 50 lines font. Without this option, 25 lines font is selected.<P>
<DT><TT>/n</TT>
<DD>Initialize text mode. Clears screen and restores default font and colors.<P>
<DT><TT>/x</TT>
<DD>Set Atari built-in font. Sets characters 0-127 to standard Atari font.
It looks better with /l option.<P>
</DL>
In Windows, font changes only in full-screen mode. Colors and number of lines change
also in a window.
