  Interrupt:   21h     Function:   4Ch
 
  Title:       Terminate Process with Return Code
 
  See also:    @Exit
 
  Description:
 
     Terminates the current process, passing a return code to the
     parent process. This is one of several methods that a program can
     use to perform a final exit.
 
     If you use the .STARTUP directive, you should also use the .EXIT
     directive, which automatically generates code to call this
     function.
