String Functions
Lighthouse Studio includes a number of string functions for operations involving text variables (such as openends, etc.).
The "Sawtooth Script" column below gives the syntax for String Functions.
Sawtooth Script: |
Description: |
IsNumber (QuestionName) |
Is true if the entire string is all digits, false otherwise. |
Length (QuestionName) |
Returns the number of characters contained in the response. |
Mid (QuestionName, BeginPosition, Length) |
Extracts a substring of a string given by QuestionName. The substring is extracted starting at the character number specified in BeginPosition (1-based counting) with length specified in Length. |
TextExists (QuestionName, "TextToLookFor") |
Searches for "TextToLookFor" in the answer of QuestionName. If found, a 1 is returned; if not found, a 0 is returned. |
ToLower (QuestionName) |
Returns a lowercased version of the response. |
ToUpper (QuestionName) |
Returns an uppercased version of the response. |
To concatenate strings, use the & operator. For example:
[% "Hello " & Name %]
If Name is an open-end question and the respondent answered "Bob" for Name, then the Sawtooth Script would return:
Hello Bob
