Stack under flow Extra logical operator or output term or missing an input term
Bad node ID Using an unassigned ID # (Reserved)
Invalid Operation A non-valid function assigned to an ID#. Example: Trying to assign the output function
to an Remote Input ID by forming output token (O3) would give this error.
Out of I/O Memory I/O program too long to fit available memory
Typical error sequence example: two input tokens are created, ENT (enter) is pressed, the CHG (change)
screen appears with an error message on the last line. Press the OK key to acknowledge error message and
return to 1
st screen pictured below. Use editing facilities (eg. BAKSP, DEL, etc.) to make corrections.

. Positive And Negative
The other 2 input functions are for use with Edges. These are called pos and neg (
P
and
N
), and
they become true only once following an Edge event occurrence. The duration of this true value is no
longer than 100 milliseconds, the interval of time between scans of the I/O program. If you test an event
within the STC-2002, you must use a Positive function. This is because Events are Edges in nature. A zero
thickness event is an example of this. Remember that States are steady state conditions and can be tested
using either input, Positive, or Negative. The positive test of an input yields TRUE once on a change from
False to True. The negative does similarly on a True to False change.
