=Types of Variables= 

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

A variable name can be letters and numbers but the first character must be a letter.  FirstName$,FirstName$, FavoriteFilmNo5$, Address2$ store strings.  Total,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 summary table of types and namesquick 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.
