WAIT
Purpose
To put the system on hold for a specified duration. In the interval, the system will be
running in a rather low power consumption mode.
Syntax
WAIT(duration%)
Remarks

This argument is specified in units of 5 milliseconds.
When the application is waiting for events in a loop, the power consumption will be
dramatically reduced by calling this function.
Example
PRINT " BASIC"
WAIT (200)
' the system is on hold for 1 second
