Functions

TSL allows you to define functions. A function can take a predefined number of parameters and
return multiple parameters if desired.
Let's define a function and call it:
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.
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)
end
sum, diff, ratio = sum_diff_ratio(2,3)
print(sum)
print(diff)
print(ratio)
Output of code above:

psum = parameter1 + parameter2
pdif = parameter1 – parameter2
prat = parameter1 / parameter2
return psum, pdif, prat
