Example String find 001

 

 

Description

This example shows the find function operating on two sets of string or text. The find function compares the first string argument with the second string argument. If the first string argument matches the second string argument, then the position of the first argument string in the second string argument is returned. The user may also specify the position in the second string argument where the search will begin using an optional integer argument. If there is no match found, then the Boolean value false is returned by the function.

 

Details

In this example, the find function starts searching at the beginning of the second string argument by default since no starting position is specified.

(find "She" "Sheldon sells sea shells") Returns: 0

In these last two examples, the starting position is specified by the integer argument 5.
Also, these examples show that the comparison between the first string argument and the second string argument is case-sensitive.

(find "She" "Sheldon sells sea shells" 5) Returns: false
(find "she" "Sheldon sells sea shells" 5) Returns: 18
