Any error number of 2000 or greater is an HTBasic extension to HP BASIC. Not all errors that can occur under HP BASIC can occur under HTBasic. The Reference Manual contains a list of errors that can occur.

 

In general, the error numbers returned for errors are the same as those returned by HP BASIC. But in some instances the operating system or environment in which HTBasic runs makes it impossible or impractical to return the same number.
