>>Alter Table would probably best solution. If you can use the Command window simulator in your apps, then you use the table exclusively and do a modify structure. If the table is part of a DBC, then you need to open the database exclusively first. Also the original table would need to be modified itself to prevent losing any persistent relationships, primary keys, long names, etc.

The simplified 'command window' is form with textbox and button. Button click event fire code:
Local cCommand
cCommand=Thisform.txtCommand.value && you type literal command in textbox
&cCommand.
