Redim Preserve

Basic syntax x(n)

Usage

Redim Preserver x(n)

Re-dimension the array x to size n, while preserving the initial values in x. x is an array and n is a positive whole number specifying the new size of n.

Examples

The following example is applicable to Basic syntax:

Dim x() As String
'Initialize first three array elements
x = Array ("a", "bb", "ccc")
'Re-size x to 4; old values are retained
Redim Preserve x(4)
'initialize x(4)
x(4) = "dddd"
'return "dddd"
formula = x(4)

Crystal syntax x[n]

• Use Redim Preserve x[n] (with the square brackets) only in Crystal syntax, and Redim Preserve x(n) (with the round brackets) only in Basic syntax.
• Unlike Redim Preserve x(n) in Basic syntax, you may not have multiple arrays in one Redim Preserve statement in Crystal syntax.

Usage

Redim Preserver x[n]

Re-dimension the array x to size n, while preserving the initial values in x. x is an array and n is a positive whole number specifying the new size of n.

Examples

The following example is applicable to Crystal syntax:

Local StringVar array x := ["a", "bb", "ccc"];
// resize the array to size 4 while preserving the old values.
Redim Preserve x [4];
// now x = ["a", "bb", "ccc", "dddd"]
x [4] := "dddd";
x[4] // returns "dddd"
