I have and am using dbase .dbf tables and Delphi/BDE with delphi
since the beta of Delphi 1 (with the exception of a short excursion
into Apollo).
Delphi with create an xbase expression as an index so that an
expression like
'fld1 + str(fld2,8,0) + dtos(fld3)'
will work fine.
I use 'locate' as my main find tool. Syntax like
table1.locate('fld1', MyValue, []);
works fine.
If you continue to have trouble - particularly with creating the
index using either the TTable method or the BDE method, let me know
and I will send code segments!
Alternatively send me some code fragments to audit.
