C++ File access routines ( convert from RDBMS)

[bloke]

Hi There,

I have recently written a pilot application using PB6
and SQL Anywhere. PB does not cater for some lower
level things I need to do now. I want to convert to
C++ and a flat file database ( indexed if possible).

Instead of a file for each table, I was hoping to do
something along the lines of Cobol file variants.

What would be the best way to implement this in C++.

I have to read/write/update lines in the file.

TIA

Chris
