I have an event history file which evidently can get corrupted.

The only time the file is written to is by this code

Select 0
Use (fname) Alias EventHistory Shared

Insert Into EventHistory (When, who, pgmname, exename, desc1, desc2) ;
	VALUES (MountainTime(),goVars.UserName, goVars.ApplicationName, Juststem(Sys(16,3));
	, lcText1, lcText2)
Use

Do I need to put some locking around this, and, if so, what would the code look like?

Thanks
