I have to run it under dBase Plus though as it does not work properly with later dBase versions. Looking for an answer to this new problem I have tried many things. Now I got it to work OK again, what did I do ? I found following files in the program directory which I deleted and the it worked ok again. > _QSQL000.DBF > _QSQL305.DBF > _QSQL317.DBF > _QSQL317.DBT > _QSQL641.DBF > _QSQL641.DBT > _QSQL645.DBF > _QSQL645.DBT These are temporary files created by the BDE under certain circumstances such as when one uses an ORDER BY clause in a query.  dBASE should delete them automatically when the application closes but sometimes they get left behind. dBASE can only create 1000 _QSQLnnn.dbf files.  Once that limit is reached it causes errors.  You can safely delete these files.
