Replace

Description

Replaces a portion of one string with another.

Syntax

Replace ( string1, start, n, string2 )

Argument

Description

string1

The string in which you want to replace characters with string2.

start

A long whose value is the number of the first character you want replaced. (The first character in the string is number 1.)

n

A long whose value is the number of characters you want to replace.

string2

The string that replaces characters in string1. The number of characters in string2 can be greater than, equal to, or fewer than the number of characters you are replacing.


Return value

String. Returns the string with the characters replaced if it succeeds and the empty string ("") if it fails.

Usage

If the start position is beyond the end of the string, Replace appends string2 to string1. If there are fewer characters after the start position than specified in n, Replace replaces all the characters to the right of character start.

If n is zero, then in effect Replace inserts string2 into string1.

Examples

This expression changes the last two characters of the string David to e to make it Dave:

Replace("David", 4, 2, "e")

This expression returns MY HOUSE:

Replace("YOUR HOUSE", 1, 4, "MY")

This expression returns Closed for the Winter:

Replace("Closed for Vacation", 12, 8, "the Winter")
