John:
The exact same code is in my FP 2.6 DOS version of ErrTrap, which was last
modified in 2000. So it will work. The 'retry' is what exits the ErrTrap with
the DBF open, without the (missing) CDX.
If you don't have a generic ErrTrap procedure, you could just do on
error do CheckCdx while opening the DBF's and then put it back.
