setLength function

The setLength function changes the size of a dynamic array. When a dynamic array is declared, its size is 0. You need to use setLength to set the number of items that the array can contain.

Use the length function to retrieve the current size of the array. Because arrays in Ultra Fractal are always zero-based, the array elements are numbered from 0 to length(array) - 1.

Examples:

int a[]
print(length(a))  ; Prints 0
setLength(a, 50)
print(length(a))  ; Prints 50
; You can now safely access a[0] to a[49].
