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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

The variable is not of the required type. For example, you

and a numeric variable, or with two numeric variables of
different types.
