Example GEL source code

Here is a sample definition of a function calculating the factorial recursively

function f(x) = (
  if x <= 1 then
    1
  else
    (f(x-1)*x)
)

GEL contains primitives for writing the product iteratively and hence we can get the following iterative version

function f(x) = prod k=1 to x do k
