function-endfunction

A function declaration consists of
- the datatype of the return value for the function
- the name of the function
- an argumentlist delimited by comma and surrounded by parenthesis. The
argumentlist must include a typedeclaration and a name for each argument.

The arguments supplied by the caller will be converted to the type of the
to the type declared in the argument list. If an argument is changed inside
the function, the new value will be transferred to the caller. In this way
it is possible to return other values then the return value of the function.
A function can contain one or several return statements. The return will hand
over the execution to the caller and return the supplied value.

Example

function float calculate_flow(float a, float b)

    float c;

    c = a + b;

    return c;

endfunction

...

flow = korr * calculate_flow( v, 35.2);
