Chapter 3 Script Syntax

Arrays

Using and Naming Arrays

 There are two types of arrays, integer arrays and string arrays.

Integer arrays are prefixed with a %. String arrays are prefixed by a

 The maximum number of elements per array is limited only by

available memory. Array elements are dynamically allocated—no size

declaration, no limits, no reallocation needed.

 The syntax for arrays is:

ArrayName[ ArrayIndex].

 Array elements are accessed by surrounding the array index with

square brackets “[ ]”.

 Arrays are indexed by a numeric expression (normal array) or a

character expression (associative array). The only limitation to index

expressions is that the index cannot be the direct return value of a

script. For example, the following statement:

$Var := $Array[ Script()]

must be written as

%Index := Script()

$Var := $Array[ %Index]

to make clear what is the index type (array type). This assumes

Script() returns a numeric value and $Array is a normal array.

 An array’s indexing type (normal or associative) is determined by the

first use of the array encountered by the compiler (processed from

script beginning to end).

 Arrays can be copied to new arrays just like any other variable, if the

destination array is new or of the same structure as the source:

$A[1] := “Hello”

$A[2] := “World”

$B := $A

// $B[1] will contain “Hello” and

// $B[2] will contain “World”

1 2 ... 33 34 35 36 37 38 39 40 41 42 43 ... 261 262
