RE: TZF - VFile at Runtime

Thanks, Randall.
That was just too easy. Something in the Topaz 7.51 manual lead me to 
believe there had to be a .DBF file on the hard drive to use in the 
statement:
   VTempDBF.DbfFilename := 'C:\YourFolder\YOURFILE.DBF';
Obviously, that is not the case since your sample works great, does not 
create a disk file, and is faster than a speeding bullet. 

Thanks again for your help. I will put this to good use.
