Problem

Solutions: File Control Block (FCB): A small block of memory initialized by DOS when it opens a file. Information about the status of a file is maintained by the File Control Block. FCBs are used by programs to provide the name and identification of opened files and their status while in use. With DOS, the traditional file services are based on FCBs. An alternative to the FCB-oriented file services works with a 2-byte number or "handle" that uniquely identifies each file that is in use by a program.

This block of memory originated with the CP/M operating system (e.g., the precurser to DOS). It was maintained in DOS to make the importing of CP/M programs easier.
