SETBLINK()
Toggle asterisk (*) interpretation in the SETCOLOR() string between blinking
and background intensity
------------------------------------------------------------------------------
Syntax
SETBLINK([<lToggle>]) --> lCurrentSetting
Arguments
<lToggle> changes the meaning of the asterisk (*) character when it
is encountered in a SETCOLOR() string. Specifying true (.T.) sets
character blinking on, and false (.F.) sets background intensity. The
default is
true (.T.).
Returns
SETBLINK() returns the current setting as a logical value.
Description
SETBLINK() is an environment function that toggles the
blinking/background intensity attribute and reports the current state of
SETBLINK(). When SETBLINK() is on, characters written to the screen can
be made to blink by including an asterisk (*) in a color string passed
to SETCOLOR(). When SETBLINK() is off, the asterisk (*) causes the
background color to be intensified instead. Thus, blinking and
background intensity attributes are not available at the same time.
Note: This function is meaningful only on the IBM PC or compatible
computers with CGA, EGA, or VGA display hardware.
Examples
. This example saves the current SETBLINK() state before passing
control to a user-defined function. Upon return, SETBLINK() is
restored to its original value:
lOldBlink := SETBLINK()
MyFunc()
SETBLINK(lOldBlink)
