PROGRAM-ERROR INDICATOR
.
•
There are two lights located to the right of the Special Function Keys on the 700
keyboard. These two lights are used as error indicators. The one on the right indicates
MACHINE ERROR; the one on the left PROGRAM ERROR. The MACHINE ERROR
INDICATOR is discussed later.
The PROGRAM ERROR INDICATOR is turned on whenever an illegal operation is
performed (i.e., taking the logarithm or square root of a negative number, or dividing by
zero). Also, if a calculated result is greater than 10 99 , the PROGRAM ERROR INDICATOR
will be turned on. Whenever the indicator is on, the arithmetic sign of the X-Register
also flashes.
