Direct Access Files
Michael Coughlan · Apress eBooks · 2014
When I learned COBOL many years ago, direct access files, and particularly indexed files, were the jewel in COBOL’s crown. No other mainstream programming language provided native support for file organizations of such versatility. Nowadays, the predominance of databases means that the importance of direct access files in modern COBOL programming is greatly reduced. Nevertheless, the huge inventory of legacy programs that still use direct access files makes these file organizations a worthwhile topic of discussion. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
