Overwrites a substring of a string with another

Syntax

declare sub Mid ( byref text as string, byval start as integer, byval length as integer, byref expression as const string )
declare sub Mid ( byval text as wstring ptr, byval start as integer, byval length as integer, byval expression as const wstring ptr )

Usage

Mid( text, start ) = expression

or

Mid( text, start, length ) = expression

Parameters

text

The string to work with.

start

The start position in text of the substring to overwrite. The first character starts at position 1.

length

The number of characters to overwrite.

Description

Copies a maximum of length characters of expression into text, starting at start.

If length is not specified, all of expression is copied. The size of the string text is unchanged; if expression is too big, as much of it is copied up to the end of text.

Mid can also be used as a function to return part of another string. See Mid (Function).

Examples

start GeSHi

Dim text As String

text = "abc 123"
Print text 'displays "abc 123"

' replace part of text with another string
Mid(text, 5, 3) = "456"
Print text 'displays "abc 456"

end GeSHi
