Arrays are allocated using the DIM command or re-sized using REDIM. They may hold numeric or string data. Access to specific elements in an array is accomplished by using square brackets along with the integer offset of the element, starting from zero. Arrays may also be dimensioned and accessed using two dimensions.
Array lengths may also be extracted using [?] [?,] and [,?] on the end of the array variable.

Assigning values to an array

Values may be assigned to an array in one of five ways:

1. By using the Dim statement to reserve space for the array in the computer's memory and then assigning each individual element.

dim a(10)
for t = 0 to a[?]-1
    a[t] = t
next t

2. By using a list to create and assign an array.

a = {{0,1,2},{3,4,5},{6,7,8}}


b[] = {1,2,3,4}

3. By using the Dim statement to copy an existing array into another array.

a = {1,2,3,4}
dim b = a[]

4. By using the Explode or Explodex functions to split a string into an array.

a = explode("how now brown cow"," ")

5. Using the fill assignment operator (with or without dim)

dim c fill "stuff"
dim e[] fill 0
b fill ""
a[] fill -1

Passing Arrays of Data to Builtin Functions and Statements

When passing an array of data, like to the sound statement, you must include an empty set of brackets [] after the variable name. This was added to reduce the confusion between a regular variable and a variable containing an array of values.
