Name: Map - Apply a procedure to each element of a list or string
Synopsis:
[v1 ... vn] {f} Map -> [ f(v1) ... f(vn) ]
(c1 ... cn) {f} Map -> (f(c1)...f(vn))
Parameters:
[v1 ... vn] - list of n arbitrary objects
(c1 ... cn) - string with n characters
{f} - function which can operate on the elements of [array].
This function must return exaclty one value.
Description:
Map works like the corresponding Mathematica function.
For each element of the input array, Map calls f and replaces
the element with the result of f.
Note that f must return exactly one value! The result of Map
is a list with the same number of values as the argument list.
If f does not return a value, Map fails.
If f returns more than one value, the result of Map is undefined.
Examples:
[1 2 3 4 5] {2 mul} Map -> [2 4 6 8 10]
(abc) {1 add} Map -> (bcd)
