replace

 

 

Overview

The replace function replaces a specified number of characters in a Text or String with another Text or String. The replace function is non-destructive

Usage

The replace function replaces only the substring at the specified index. The replace function is similar to the substitute function, except that substitute can replace any or all of the occurrences of the specified substring whereas replace only replaces one at a specified position in the String.

 

Syntax

Expression:

(replace old-text start length new-text)

Arguments Name Type Description
Argument:old-textString or Text A String object or Text that contains the text to be replaced.
Argument:startInteger A positive integer indicating the position of the first character in old-text to be replaced. Set start to 0 for the first character, 1 for the second and so on
Argument:lengthInteger A positive integer representing the number of characters, after the starting position, to be replaced.
Argument:new-textString or Text The Text or String to be inserted in old-text at start, replacing the specified characters. new-text does not have to be the same length as length

Returns:

The result string after the replace has been done
