Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

Expressions and Operators
 
An expression can be a string constant, numeric constant, a variable, or a
single value obtained by combining constants, variables, and other
expressions with operators.
 
Operators perform mathematical or logical operations on values. The
operators provided by BASIC can be divided into five categories:
 
  Category                  Task
 ◄Arithmetic Operators►     Perform calculations
 ◄Relational Operators►     Compare strings and numeric values
 ◄Logical Operators►        Test conditions or manipulate individual bits
 ◄Functional Operators►     Supplement simpler operators
 ◄String Operators►         Combine and compare strings
