COLOR [DUAL MODE]
NAME COLOR - set the colors on the display
SYNTAX

where

basiccolor =

ULT]
USAGE
Color is used to set the foreground and background color
of a session. It affects only the session, where it is
run. If you want to set the colors in all sessions, you
must create a command file, where the color-command with
desired parameters is run and then you must modify your
config.sys. If you set as the last parameter of your
protshell-line the following " /K cmd-file", OS/2 will
run the cmd-file every time you start a new session. Note
that starting an OS/2 Window does not start a new
session.
Color uses Vio-calls except in OS/2 Window, where the
call used for changing colors does not work. In OS/2
Window color uses ANSI-escape sequences, which limit its
capabilities to the basic colors. E.g. RED is supported,
but not LIGHT_RED or DARK_RED.
Color uses ANSI escape sequences. If the ANSI sequences
are off, color sets ANSI on for the duration of the
program and restores the original situation at the end of
the program. OS/2 seems to work in a random fashion in
this kind of situations. Sometimes the colors change
sometimes not. The color sets the current cursor position
to the bottom of the screen, because with my version
(1.21) the ANSI- sequences worked every time, when the
cursor was at the bottom of the screen. Still CLS-command
seems to reset all color to their default value, if ANSI
is off.
