The information in this article applies to:

  • Microsoft FoxBASE+ for MS-DOS 2.1

This article was previously published under Q101797


You receive the

Operand Missing

error message when you use FoxCentral and attempt to use an index on a database.


FoxCentral saves all information about its environment in two files called CENTRAL.ADM and CENTRAL.ADX. This environment information includes frequently used databases and any indexes associated with them. Because FoxCentral saves this information in these two files, if the databases saved in these environment files are modified outside FoxCentral, the information saved in the files can become outdated or invalid.


To work around this problem:

  1. Quit FoxBASE+ and rename the files CENTRAL.ADM and CENTRAL.ADX to CENTRAL2.ADM and CENTRAL2.ADX using the MS-DOS RENAME command.
  2. Restart FoxBASE+ and go into FoxCentral.

You should now be able to use the database and its corresponding index without a problem.


FoxCentral is the nonprogramming user interface in FoxBASE+ for MS-DOS that gives users access to the most powerful FoxBASE+ commands without doing any programming.
