Name
Input Variable
Syntax
var Input: TextFile;
Description
The Input variable is a text file that Delphi
automatically opens for reading, but only in console applications.
The input file is usually the console, but the user can redirect
input from the command shell.
Input is an ordinary TextFile,
and you can close it or open a different file. If you open a file
without a name, that is the same as opening the console file. For
example, Delphi always performs the following when a console
application starts
running:
AssignFile(Input, ''); Reset(Input);
Calling Read or ReadLn without
a file reference as the first argument is the same as calling
Read or ReadLn using
Input as the first argument.
