<lang euphoria>function apply_to_all(sequence s, integer f)
-- apply a function to all elements of a sequence
sequence result
result = {}
for i = 1 to length(s) do
-- we can call add1() here although it comes later in the program
result = append(result, call_func(f, {s[i]}))
end for
return result
end function
function add1(atom x)
return x + 1
end function
-- add1() is visible here, so we can ask for its routine id
? apply_to_all({1, 2, 3}, routine_id("add1"))
-- displays {2,3,4}</lang>
This is also "Example 2" in the Euphoria documentation for <code>routine_id()</code>.
Note that this example will not work for multi-dimensional sequences.
