Defines the standard output text file System unit
var Output : TextFile;
The Output variable is predefined by Delphi to refer to the standard text output file.
This is normally the console, but may be overriden to any file using the Assign statement.
Output is used in the text file Write, WriteLn and Seek routines. It may be omitted in these commands however, since it is the default file.
