Functions
TSL allows you to define functions. A function can take a predefined number of parameters and
return multiple parameters if desired.
Here is an example of how to define a function and call it:
function add_two(parameter1, parameter2)
return(para parameter2)
end
print(add_two(3, 4))
Below is an alternate syntax for defining a function. Functions are first-class values in TSL, which
means functions can be stored in variables, passed as arguments, and returned as results if
desired.
add_three = function(parameter1, parameter2, parameter3)
return(para para parameter3)
end
print(add_three(3, 4, 5))
Here is a function that returns multiple parameters; sum, difference, and ratio of the two numbers
passed to it:
function sum_diff_ratio(parameter1, parameter2)
psum = para parameter2
pdif = parameter1 – parameter2
prat = parameter1 / parameter2
return psum, pdif, prat
end
sum, diff, ratio = sum_diff_ratio(2,3)
print(sum)
print(diff)
print(ratio)
