Disassociate Procedure

The predefined procedure disassociate removes the logical-physical file association that was previously created with the standard procedure associate. As a result, you can no longer use the file f with Pascal input and output routines.

Syntax

disassociate (f)

Parameters

Normally, a file is closed on exit from the block in which it is declared. A disassociated file, however, remains open until it is closed with a direct call to an operating system routine.

Disassociate is useful on a file that is opened by a non-Pascal routine that is passed to a Pascal routine and must remain open on exit from the Pascal routine.
