Retrieves the current SIMPL signal number associated with a particular input or 
output. This is generally used to determine if a particular input or output on a gate is 
being used, and generally used with arrayed inputs or outputs. This can be used to 
build a gate of a predetermined maximum size, and allow the user to add and subtract 
signals on the input or output of the gate (i.e., the program would be written to iterate 
through a DIGITAL_INPUT array until IsSignalDefined returns a 0). 

Legal output and input signal types are ANALOG_INPUT, ANALOG_OUTPUT, 
BUFFER_INPUT, DIGITAL_INPUT, DIGITAL_OUTPUT, STRING_INPUT, 
STRING_OUTPUT.

The particular input or output is tied to an integer giving the signal number. If a signal 
has been tied to that input or output of the gate, a non-zero value will be returned. If 
the signal is tied to 0 on the SIMPL gate or the signal is not defined, then 0 will be 
returned. If the signal is tied to 1, then 1 is returned.

DIGITAL_INPUT INS[20];

INTEGER NumInputs;

 

FUNCTION MAIN()

{

FOR(NumInputs = 20 to 1 Step -1)

IF(IsSignalDefined(INS[NumInputs]))

Break;

}

This example computes how many inputs are used on the gate. It should be noted that 
it is useful to work backwards from the end of the gate. If the user tied five signals, a 
0, and then five more signals, this would yield the correct result that the 11th input 
was the last one used.
