Functions take one or more comma-separated parameters and return a result. The 
following template shows how each language construct and function is explained. 

The name used to refer to the construct or function. 

The SIMPL+ specific language requirements for this particular construct or function. 
This section demonstrates exactly how to enter the statement in a SIMPL+ program.

For completeness, the general syntax for SIMPL+ functions is shown below:

<Return Value Type> FunctionName(<Parameter 1 Type> [,

<Parameter 2 Type> ...]);

The Types are described as STRING, INTEGER, LONG_INTEGER, 
SIGNED_INTEGER, and SIGNED_LONG_INTEGER. 

If a STRING is specified as a return type, a STRING or STRING_OUTPUT variable 
may be used. 

If an INTEGER or LONG_INTEGER is specified as a return type, an INTEGER, 
LONG_INTEGER, ANALOG_OUTPUT or DIGITAL_OUTPUT may be used. 

If a STRING is specified as a parameter, a STRING, STRING_INPUT, 
BUFFER_INPUT or literal string (i.e. “Hello””) may be used.

If an INTEGER,  LONG_INTEGER, SIGNED_INTEGER or 
SIGNED_LONG_INTEGER is specified as a parameter, an INTEGER, 
LONG_INTEGER, ANALOG_INPUT, ANALOG_OUTPUT, DIGITAL_INPUT 
or DIGITAL_OUTPUT may be used. A literal integer (i.e. 100) may also be used. 
Note that for DIGITAL_OUTPUT values, a value of 0 is equivalent to digital low, 
and any other value is a digital high.
