EXPRESSIONS
AND OPERATORS
An expression may be a string or numeric
constant, a variable, or a combination of
constants and variables with operators. An
expression always produces a single value.
Operators perform mathematical or logical
operations on values. The GWBASIC
operators may be divided into four categories:
• Arithmetic
• Rslational
• Logical
• Functional
Each category is described in the following
subsections.
