$Variable$ is a custom-named text variable that is equal to a constant or one of the other variables listed. The name between the $ may be up to 20 characters long. Spaces are not allowed, but you can use the underscore (_) and dash (-) as separators. The text value is not case sensitive. If the value of $variable$ contains all digits, the value is evaluated as a number and not text. For example, Tuesday, TUESDAY, and tuesday are all equivalent text values. The variable 6 would be evaluated as less than 1234, but 6a would be evaluated as greater than 1234zzz.

Common uses include:

  • Allowing variables meaningful names.
  • Providing a user-named variable for testing with an IF statement.
