Out(0) = In(0) + In(1);

Out(0) = In(0) - In(1);

Out(0) = In(0) * In(1);

if (In(1)) Out(0) = In(0) / In(1);	
	
If In(1) == 0.0 the output will not be updated

Out(0) = (In(0) > 0.0 ? In(0) : -In(0));

if (In(1) != 0.0) 
	{
	Out(0) = ((int)In(0)/(int)In(1));
	Out(1) = ((int)In(0)%(int)In(1));
	}
						
If In(1) == 0.0 the output will not be updated )
Provides integer operation but all inputs and outputs are floats 

Out(0) = (int)In(0);
Out(1) = In(0) - Out(0);

Out(0) = ceil(In(0));
Out(1) = floor(In(0));

Out(0) = exp(In(0));
Out(1) = log(In(0));

Out(0) = pow(In(0), In(1));

Out(0) = sin (In(0));

Out(0) = cos (In(0));

Out(0) = Out(0)+In(0)*In(1);

Simple scaled integral
In(2) provides update step interval

Out(0) = Out(0)+(In(1)*(In(0)-Out(0)));

Simple scaled difference
In(2) provides update step interval

Out(0) = In(0) >= In(1) ? 1.0 : 0.0;

Out(0) = In(0) >= In(1) ? In(0) : In(1); 
Out(1) = In(0) >= In(1) ? In(1) : In(0);

Out(0) = fabs(In(0)) >= fabs(In (1)) ? In(0) : 0.0;
	
Out(0) is zero if In(0) is less than the magnitude of In(1)
Out(0) follows In(0) whilst it is >= the magnitude of In(1)

(as usual 0.0 => false, any non zero => false, true output => 1.0)

Out(0) = In(0) && In(1);

Out(0) = In(0) || In(1);

Out(0) = (In(0) || In(1)) && !(In(0) && In(1)); 

Out(0) = !In(0);

if (In(0)) Out(0) = Out(0) ? 0.0 : 1.0;

if (In(1)) Out(0) = In(0) ? 0.0 : 1.0; 

Out(0) = user entered constant

Out(0) = Out(1); Out(1) = In(0); 
(uses Out(1) to store the previous value)

Implements a simple digital filter.
In(0) - signal in, In(1) - sample control, Out(0) - filtered output
The sample rate sets the frequency response
Low pass and high pass frequncy = 1/8 of the sample rate
Band pass allows frequnciesbetween 1/2 and 1/4 of the sample rate

if (In(0)) Out(0) = In(1) ? Out(0) + 1.0 : Out(0) - 1.0;
if (!In(2)) Out(0) = 0.0;
			
Implements an up/down counter
In(0) pulse input - must toggle zero/non-zero
In(1) direction - 0.0 => down, non-zero => up
In(2) will rest the counter (when non-zero)

Implements a (seconds) timer
Out(0) is the elapsed time from reset
In(0) will rest the timer (when non-zero)
The user can set the rate at which the output is updated

Variable frequency square wave (0.0, 1.0) output
The user sets the period (1/2 * frequency)
In(0) will rest the ticker (when non-zero)

if (In(1)) Out(0) = In(0);
	
While In(0) is non-zero Out(0) follows In(0)
When In(0) goes to zero the last output value is held

if (In(1) && !Out(1)) Out(0) = In(0);
Out(1) = In(1) ? 1.0 : 0.0;
					
In(0) is instantaneously sampled when In(1) goes from zero
Out(0) remains fixed until the next sample (rising edge of In(1)
Out(1) hold last state of In(1)

Creates a user input entry box at the bottom of the window

Creates a box which displays its input

Creates a child window displaying an x-y graph
In(0) has the y value, In(1) has the x value
The graph has -1 < x < +1, and -1 < y < +1
The scale and offset can be set to create values in this range
ie -1 < ((input * scale) + offset) < +1
The graph is only updated on a change of x - In(1)

Creates a child window displaying an y-t chart
In(0) has the y value, In(1) steps the chart forward
The graph has -1 < y < +1
The scale and offset can be set to create values in this range
ie -1 < ((input * scale) + offset) < +1
The graph is updated on a change of In(1) from zero to non-zero

Creates a module - a function made up of other functions
The user specifies the numbers of inputs and outputs
Right click the top left corner hot spot to descend into a module
- or ascend from one.

Povides an interface to an external Perl script
The deltaFSD function will then execute a Perl sub in the script

The first invocation requires the script file
Then user specifies the sub name and the numbers of inputs and outputs
See the notes in the samples section for more information

Creates a bidirectional socket (stream) interface
Data is transferred as comma separated channel,value pairs
The default port number is 6739
The user specifies the numbers of inputs and outputs
deltaFSD acts as a server so clients can connect from anywhere - "localhost" or via network
See the notes in the samples section for more information
