| Description |
The Input variable is predefined by Delphi to refer to the standard text input file.
This is normally the console, but may be overriden to any file using the AssignFile statement.
Input is used in the text file Read, ReadLn and Seek routines. It may be omitted in these commands however, since it is the default file.
