 Basic Data Types Summary
 
 ■ A data type refers to the variable attribute that determines the kind
   of data a variable can hold. Supported data types include INTEGER, LONG,
   SINGLE, DOUBLE, CURRENCY, and STRING. Special data types include FORM,
   CONTROL, and user-defined.
 
 ■ Valid suffixes, sizes, and ranges for Basic data types are listed below.
   Some values differ for ISAM specific types. See: ◄ISAM Data Types Summary►
 
 ■ Data type names accepted in AS type declarations are shown in uppercase
   letters. See: ◄AS Declaration Statements►

 ■ Use the LEN function can be used to return the size of a variable. The
   FRE function can be used to approximate the memory size of a form or
   control. See: ◄FRE Function►  ◄LEN Function►
