Functions

TSL allows you to define functions which can take a pre-defined number of

parameters and return multiple parameters. Functions are first-class values in

TSL, which means that they can be stored in variables, passed as arguments,

and returned as results if desired.

This is a function called "add_two":

function add_two(parameter1, parameter2)

return(parameter1 + parameter2)

end

print(add_two(3, 4))

This is an alternate syntax for defining a function, called "add_three":

add_three = function(parameter1, parameter2, parameter3)

return(parameter1 + parameter2 + parameter3)

end

print(add_three(3, 4, 5))
