=Types of Variables= 

In the [[0304|Define Variables]] lesson we learned Liberty BASIC has two types of variables: **numbers** and **strings**. If the last character of the variable name is a dollar sign **$**, it holds a string. If it does not have a **$** on the end, it holds a number. What could be easier?

A variable name can be letters and numbers but the first character must be a letter. FirstName$, FavoriteFilmNo5$, Address2$ store strings. Total, price12, and count3 hold numbers.

In these next few lessons we will be learning much more about them ... and the power they possess.

Here is a quick chart you can use to test what you've learned. Use one hand to cover all but the first column. Is each variable a number, string or illegal name. Then remove your hand to check your answers.
|| Cookbook$ || string || begins with letter, end with $ ||
|| Temperature || number || begins with letter, no $ on end ||
|| rainbow || number || begins with letter, no $ on end ||
|| snowflake$ || string || begins with letter, ends with $ ||
|| snow% || illegal || percent (%) can not be in name ||
|| 37acorns || illegal || begins with a number ||
