Open a text or binary file for write access System unit
1 procedure ReWrite(var FileHandle TextFile);
2 procedure ReWrite (var FileHandle File {RecordSize ;
The ReWrite procedure opens a file given by FileHandle for writing.
You must use AssignFile to assign a file to the FileHandle before using Reset.
If the file does not exist, it is created.
If the file already exists, the contents are lost, and new data is added to the start.
Use Write or WriteLn to write to the file after this ReWrite is executed.
Version 1
Is used for text files.
Version 2
Is for binary files. The optional RecordSize value is used to override the default 128 byte record size for binary (untyped) files. For such files, only BlockRead and BlockWrite can be used.
