ASCII tables?

Hi
Does anyone know how to properly access TXT files with Delphi4 using  BDE
build-in ASCII Driver ??

According to the Borland TI892D, I was using *.SCH files for fields
definition, and it worked fine under Delphi 2. But it seems inefficient with
Delphi 4  : my app see the whole line as one field...

Thanks,
Fred.
