Statement

Function <returntype> <name>([<parameters>]);

Function is a reserved word used to start the code of a function.

Concept

A function is a subroutine to which one or more of the following apply:

• it receives parameters
• it acts on the parameters
• it processes data located elsewhere
• it returns a value

A function does not create a new thread, and therefore the process which called the function waits until the function is completed before continuing executing its code.

As opposed to a process, a function doesn't have a frame; statement. See process for more information.

For a list of functions, see this list of functions.

Example

Function int addInts( int a , int b )
Private // Declare private variables here
Begin // Start the main functioncode
    return a+b;
End // End the main functioncode

addInts(3,6); will return 9. One can see that the function does indeed:

• receive parameters.
• act on the parameters.
• return a value.
