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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

Certain internal limitations of QBasic have been exceeded.
 
For example, during expression evaluation, strings that are
not associated with variables are assigned temporary
locations. A large number of such strings can cause this
error to occur. Likewise, a numeric expression made up of
many complicated subexpressions can cause this error.
 
Try simplifying expressions or assigning strings to
variables.
