Is it possible that the dbf has been modified and is no longer usable by fp dos?


>Is anyone familiar with SBT running on Foxpro for DOS v 2.6? I have a client who is running SBT and has come across a problem. The consultant who implemented SBT is long gone and I just got a call. They have instructions to run a program called 'SYSFLG.PRG' to fix issues when tables get locked. When running this program, when we encounter the 'USE sysdata' line, the program returns an error 'Not a database file'.
