handle=fopen("mytable.dbf",12)
>>=fseek(handle,28)
>><d>lnPokeByte = bitand(fread(handle,1),0xFE)</d> && Remove CDX flag
>lnPokeByte = bitand(asc(fread(handle,1)),0xFE)

Minor correction:

=fwrite(handle,CHR(lnPokeByte),1)

>>=fclose(handle)

Of course you should also check if you can have the handle and why not too.
