| Syntax      | Find (String lookFor, String lookIn)                                                                                                                                                                                           |
| Purpose     | Searches the string specified in lookFor in the lookIn string.                                                                                                                                                                 |
| Description | Returns an integer representing the starting position of lookFor, in lookIn. If lookFor was not found in lookIn or either lookFor or lookIn is null, -1 Is returned. **Note:** Counting is started with the integer value, “0” |
| Return Type | Int64                                                                                                                                                                                                                          |
| Parameters  | <p>lookFor \[System.String] – String to search for</p><p>lookIn \[System.String] – String to search in</p><p>isCaseSensitive \[System.Boolean] – Is Case Sensitive</p>                                                         |

**Example**

In this example, we are passing the required parameters to the function transformation object using a *Variables* object.

Where,

*lookFor* = e

*lookIn* = ABCDEFGH

*isCaseSensitive* = False

Right-click on the function transformation object and select *Preview Output.* You can see that Astera Data Stack has returned the integer value “4”, indicating that the *lookFor* value’s positional integer value in the *lookIn* string is “4”.
