Some keys are prefix keys which don't generate any symbol by
themselves but modify the following keystroke. For example, on most
European keyboards the apostrophe key (') causes the next letter to be
accented. To produce an apostrophe by itself, press the apostrophe
key followed by the space bar. Other keys which may behave as
prefixes, depending on the current keyboard layout, are the backward
apostrophe (`), tilde (~), and caret (^).
Some keys represent symbols which are not available in all code
pages. For example, the German keyboard can produce a capital A
with a caret above it. In the default German code page 850, that
symbol is represented by the code 182. However, in the alternate
German code page 437, there is no such symbol. If you are using the
German layout and code page 437 to produce a capital A with a caret
above it, you get a caret character followed by a capital A (^A).
Note that the keyboard code page could be set not to match the display
code page. This can lead to confusion, as the keyboard may produce
characters which appear on screen as other symbols. Continuing the
above example, if you are using the German layout with keyboard code
page 850 and display code page 437, to produce a capital A with a
caret above it, you see a graphic box drawing character on your
screen.
Putting It All Together
To configure your system completely, you need to include commands in
your CONFIG.SYS and AUTOEXEC.BAT files. The following sample
files set up a computer to use German conventions, to switch the
keyboard layout to German, and to use code page 850 for sorting,
upper-case conversions, and the display. The commands relevant to
international issues are shown in bold type; other typical commands
are shown in normal type.
COUNTRY.SYS is assumed to be in the root directory of the boot drive,
and DISPLAY.SYS, EGA.CPI, KEYB.COM and KEYBOARD.SYS are
assumed to be in the c:\DOS directory.
