The use of Peek with a TTzVFile is perhaps justifiable with large files.
The principal advantages are:
- Peek doesn't make convertions.
- Peek doesn't move the tested record in the buffer: You need to "Go" to
the record that is found to see it.
The problem comes if Peek find a record marked as deleted (" Peek (0, n) =
'*' "):
As far I'm concerned, I didn't succeed to Peek on Field [0] to test if the
record is deleted or not.
I had to find an other way: you will find one possibility in my example.
Gerard.
