 3 Function:  The old command retrieves a file that has previously been
 4 saved either in the user's home directory or another directory to which
 5 the user has access.  If the retrieval is successful, the saved file
 6 replaces the current file and the alter file is cleared.  If the saved
 7 file's name includes a language component, the system is changed to
 8 that language.  Otherwise, the message "enter system:" is printed and
 9 the user can type basic, dbasic, or fortran.
