Types of Variables


In the 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.
