Variable Declaration

When you store a value to a variable and the variable does not exist, Visual FoxPro implicitly declares it. Languages that require explicit declaration of variables will return an error.

In Visual FoxPro, you do not assign a data type to a variable (although it is recommended that you name your variable with a prefix suggesting the data type you will use it for). Other languages require that you assign a data type to a variable when you declare it.

Visual FoxPro BASIC
