<paragraph id="par_id3147264" role="paragraph" xml-lang="en-US">A constant is a variable that helps to improve the readability of a program. Constants are not defined as a specific type of variable, but rather are used as placeholders in the code. You can only define a constant once and it cannot be modified. Use the following statement to define a constant:</paragraph>
<paragraph id="par_id3150542" role="paragraph" xml-lang="en-US">CONST ConstName=Expression</paragraph>
<paragraph id="par_id3150400" role="paragraph" xml-lang="en-US">The type of expression is irrelevant. If a program is started, $[officename] Basic converts the program code internally so that each time a constant is used, the defined expression replaces it.</paragraph>
