System Unit
Creates and opens a new file.
Declaration:
procedure ReWrite(var F: File[; RecSize: Longint ] );
Remarks:
F is a file variable of any type which was previously
associated with a file name by a call to
Assign.
RecSize indicates the size in bytes of each record
and can only be passed if F is an untyped file.
Note that RecSize is not limited to 65,535 (64K) bytes.
If F exists or is open when ReWrite is called,
F is closed, deleted, and then recreated.
If F is assigned to an empty string (‘’),
standard input is used. Text files are created
as write-only. With {$I-}, IOResult
returns an error code if an error occurred, otherwise it is set to zero.
