BASIC Programming/Beginning BASIC/Variables and Data Types
Variables allow you to store and change information. Below is an example how to use variables.
Example Code for Variables
editExample 1 (qBasic)
CLS
ASTRING$ = "Hello World"
ANUMBER% = 10
PRINT ASTRING$
PRINT ANUMBER%
Example 1.2 (freeBasic)
Cls
Dim aString As String
Dim anInteger As Integer
aString = "John Doe"
anInteger = 42
Print aString
Print anInteger
Sleep
End
Output
editExample 1
Hello World 10
In Basic, a string variable ends in a $, and whole number variables, known as integers, end with a %.
Example 2
John Doe 42
If you use Dim varName As DataType to declare variables, you do not need to use a suffix.
Arrays
editAn array is a collection of values.
Cls
Dim aNames(3) as String
aNames(1)="John Doe"
aNames(2)="Jane Doe"
PRINT aNames(1)
PRINT aNames(2)
