FBWiki: KeyPgOpStringIndex

Operator [] (String index)

Returns a reference to a character in a string

Syntax:declare operator [] ( byref lhs as string, byref rhs as integer ) as ubyte declare operator [] ( byref lhs as zstring, byref rhs as integer ) as ubyte declare operator [] ( byref lhs as wstring, byref rhs as integer ) as T

Note that Operator {} (String index) returns a reference. See [CompilerFAQ Compiler FAQ]].

Usage:result = lhs [ rhs ]
Parameters:

lhs

The string.

rhs

A zero-based offset from the first character.

T

The wide-character type (varies per platform).

Description:

This operator returns a reference to a specific character in a string.

The user must ensure that the index does not exceed the range "[0, Len(lhs) - 1]". Outside this range, results are undefined.

Examples:

Dim a As String = "Hello, world!"
Dim i As Integer

For i = 0 To Len(a) - 1
Print Chr(a[i]);
Next i
Print

Will print

Hello, world!
