Sleep: Difference between revisions

The Ada delay statement takes an argument of type Duration, which is a real number counting the number of seconds to delay. Thus, 2.0 will delay 2.0 seconds, while 0.001 will delay 0.001 seconds.

PRINT "Sleeping..."

SLEEP sec

"SLEEP" with no argument will sleep until a button is pressed on the keyboard (including modifier keys such as shift or control). Also, pressing a key while SLEEP is waiting for a specific amount of time (as above) will end the SLEEP.

The function <tt>sleep</tt> needs seconds, which are read from the standard input.
