Function Procedures

Function Procedures return values. you can use Function statement to write your own Function procedures.

Like a Sub procedure, a Function procedure is a separate procedure that can take arguments, perform a series of statements, and change the value of its arguments.

Syntax:

[Private|Public][Static]Function procedurename (arguments) [As type] statements
End Function

Note that:

1.You call a function by including the function procedure name and arguments on the right side of a larger statement or expression (returnvalue = function()).

2.Function procedures have data types, just as variables. This determines the type of the return value.

3.You return a value by assigning it to the procedurename itself.

Example:

Public function Addition(a,b)
Addition=a+b
End Function

Here Function addition is declared .It takes two arguments and then add these two values. It returns sum of two values.
