Is it possible to insert a line somewhere but not at the last line?because I
try and it put it at the end of the lines, or must I take Paradox tables ans
not dbase?

Hello,
It is uncommon a database application be based on the
phisical record order. You can order the records by creating
indexes on the columns you are interested in. That is the
role of the primary key and other secondary indexes.
No matter you use dBase or Paradox tables the problem
will remain the same. Imagine the time consumption on
open the database table file and creating the space for
a new record by moving all the subsequent ones to the
next position ! Your application will not have a good
performance!
Have a look at the topic "Sorting records with indexes"
in the C++Builder Help file.
HTH
A bientôt.
Jayme.
