Splitting strings divides a single string into two substrings. You can divide the string at a certain character, such as a carriage return, or at a word or phrase.
Select the Search/Split String function from the Functions»String»Additional String Functions palette and place it on the block diagram.
Wire the string you want to split to the string input of the Search/Split function.
Enter the text that indicates where string should be split in the search string/character input of the Search/Split String function.
In offset, enter the number of characters in string to skip before the Search/Split String function starts searching for the text in search string/character.
Wire the substring before match and the match + rest of string outputs of the Search/Split String function to string indicators or VIs or functions that accept a string as an input.
