Writes the attributes contained in the string attrs, beginning at col, row,
without affecting the characters that are on screen. The string attrs can be the
result of a
ReadAttr function, or you can build your own attribute string;
in this case, keep in mind that every attribute is treated as a character,
not a number (see example). Returns the number of attributes written, or
undef on error.
$CONSOLE->WriteAttr($attrs, 0, 0); # note the use of chr()... $attrs = chr($FG_BLACK | $BG_WHITE) x 80; $CONSOLE->WriteAttr($attrs, 0, 0);
