←OUTPUT and output.←

The results printed by your programs go inot a file called OUTPUT.  this is
only a temporary name for the file, used while your program is being
executed.  When the program is finished, the file is saved in your
directory, under another name.  Reasons for this system are:

(1) You may want to execute the same program several times, and keep all
the output files; they need distinct names.

(2) You may want to execute different programs, all of which call their
result files OUTPUT, and keep all the output files; again, they need
distinct names.

(3) The system for naming files varies from one computer to another.  The
Pascal standard can't accomodate all of them.  At LOTS, for example, a file
name has three parts, separated by periods; the third part is a number.

When you execute a Pascal program at LOTS, after translating the program
into machine language the executive program will ask 
OUTPUT=
and wait for you to type the permanent name of your result file.  I
normally use the program name, followed by a ".OUT".
