Dave,

A complete list of the Q&A Error Codes as provided to the Q&A User Group can be downloaded from here:

Meanwhile, here is the list of 08 codes.

-----------------------------------------------------
ERROR CODES - 08??

These errors typically indicate problems with the report module and Program Spec. They are often not fatal to the database and can often be repaired using the recommended procedures.

Possible solutions:
Re-compile the Program Spec (or Derived Columns screen) by making
    a change to it then pressing F10. If that doesn't work, try
    simplifying the spec until the problem disappears.
Check access rights to Temp File Subdirectory if the error is
    related to temp files
Try Copy Design/Records.

Below is a listing of all known 08?? error codes. If you encounter an error code that is not on this list, please contact Technical Support for assistance.
Many of these codes are described with very cryptic meanings. Do not be concerned if their meaning is undecipherable. Try the suggested solutions and then call Technical Support for assistance if necessary.
