Problem Statement

A common practice in computing is to send error messages to a different output stream than normal text console messages. The normal messages print to what is called "standard output" or "standard out". The error messages print to "standard error". This separation can be used to redirect error messages to a different place than normal messages.

Show how to print a message to standard error by printing     Goodbye, World!     on that stream.

Let's start with the solution:

outfile-id
  stderr to outfile-id
  ." Goodbye, World!" cr
to outfile-id
