FUNCTION:
_Wait( nSeconds ) --> NIL
PARAMETERS:
nSeconds : number of seconds to pause program execution
SHORT:
Pause program execution for nSeconds, regardless of keyboard activity.
DESCRIPTION:
_Wait() stops program execution much like inkey(). The difference is
that unlike INKEY(), which continues as soon as a key is pressed,
_Wait() waits the number of seconds specified regardless.
It is useful where you need to display a message and be sure that no
pending keyboard keystrokes vanish it before it can be read.
There is no return value from this function.
NOTE:
Keyboard input is still buffered while waiting and will be processed as
soon as the wait period is expired.
See also: _WaitFor() which stops program execution until one of a set
of specified keys are pressed.
EXAMPLE:
_Wait(5)
Result: Program execution pauses for 5 seconds no matter what the user does
on the keyboard.
