          TENEX Interface To UCSB's Simple-Minded File System

I.  PREFACE

   A subsystem for TENEX called SMFS has been written to interface

   ARPANET TENEX users to the Simple-Minded File System at UCSB-MOD75

   (see NIC 5834 / RFC 122 and NIC 11917 / RFC 399).  The Simple-Minded

   File System is a resident server process at UCSB which currently

   manages approximately 10K pages of on-line, direct-access storage.

   Using the simple command language or the subsystem here described,

   the user can transfer files to and from UCSB, and delete and rename

   them while they reside at Santa Barbara.  Files stored at UCSB may be

   read and/or write protected, and a file archived to UCSB from the

   TENEX system can be retrieved from another.

   This document is intended to provide users with the information

   necessary to use SMFS from a terminal; the reader is assumed familiar

   with TENEX.

   SMFS is currently installed at SRI-ARC (note in particular that the

   ARC EXEC WILL NOT give the user any 'GENERAL SUBSYSTEMS NOT AVAILABLE

   FOR NIC USE' flack about invoking SMFS).

   Copies of the source file are available upon request from the NIC.

   Bug reports and comments upon the code and documentation are

   solicited by the author, and may be sent to JEW through the Journal.

II.  LIMITATIONS

   SMFS can archive at Santa Barbara any file resident in a TENEX file

   system except:

      (1) Long files (in the strict, TENEX sense), and

      (2) Files whose directory name, filename, or extension contains

          other than alphameric characters, or whose combined length

          exceeds 32 characters (this limitation arises because of

          naming restrictions imposed at UCSB).

III.  OPERATING INSTRUCTIONS

   SMFs is invoked like any other subsystem --- by typing its name

   followed by a carriage return (CR).  SMFS responds with the herald

   'UCSB Archival System (ver n date)' followed by its prompt character

   '#'.  Whenever SMFS types its prompt character, it expects the user

   to respond with a command ('?' will generate a list of all valid

   commands).

   The user selects a command by typing its first letter (here and

   throughout the exchange, upper- and lower-case alphabetics are

   interchangeable).  SMFS acknowledges a command it recognizes by

   typing the remaining characters of the keyword, and rejects those it

   doesn't by typing '?'.

   If the command requires arguments, SMFS prompts the user for each one

   in turn by describing it in parentheses.  If the argument is a

   keyword, SMFS will list the set of alternatives (separated by

   slashes).  The user selects one by typing its first letter.  Again,

   SMFS acknowledges a valid selection by completing it; if the user's

   response is in error, SMFS prompts for the parameter a second time.

   If the argument is not a keyword (e.g., a filename), the user enters

   an appropriate character string terminated by a CR.  Commands with no

   predicate are sim...
