An array is defined in Gamma with the array function, which creates the array and sets the elements to the specified values.

Gamma uses the familiar square brackets [ ] syntax to reference array elements. Although Gamma has the functions aref and aset for reading and writing specified elements of the array, the square bracket syntax is normally used. An array is automatically re-sized if an element beyond its current size is set. Arrays do not have a type, and array elements can be of different types. Array elements can be set to literals (including expressions protected from evaluation), as in the following example:

Gamma> x = array (3, "hi");
[3 "hi"]
Gamma> x[3] = #a + 5;
(+ a 5)
Gamma> x;
[3 "hi" nil (+ a 5)]
Gamma> a = 8;
8;
Gamma> eval(x[3]);

	Generally, literal arrays should be avoided except for static variables. A literal array is embedded into your code. If it is changed, then the code is effectively changed!
