# Substring Tab

The Substring tab is used to create substrings for fields.

## Children Can Substring Value of This Field

If this option is checked, then children tags to this tag can be substrings.

## Substring this Field

Substrings can be used to output partial values of a parent tag. For example, suppose the parent tag of this tag points to a telephone number. The substring start and length properties can be used to output parts of the telephone number field.

## Start

The start value points to the position in the string you want the substring to start.

## Length

The length value tells Genesys Agent Scripting the number of characters to place in this value. If you leaves the length value blank, Genesys Agent Scripting will output the value starting from the start value until the end of the string.
