Q

Where in the script are functions defined?

A

A function can be defined at any place in the script.Defining a function does not call the function, it just creates the resource for it.

The definition must have been executed once before the function can be called, else you get a runtime error.

Example Code:

function newMainStateMachine()

    local sm=newStateMachine()

    local STATE_Init=0

    local STATE_InitStacks=1

    local STATE_Subscribe=2

    local STATE_Run=3

    local STATE_Error=100

    local STATE_NotSupported=200

    sm.INPUT_None=0

    sm.INPUT_Error=1

end
