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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.
Element not defined
You have attempted to use an element that you have not
defined previously as part of a user-defined data type.
 
For example, if you defined MYTYPE as containing elements
A, B, and C, and you attempted to use the variable D as
an element of MYTYPE, this message would appear.
