     The options recognized by ERASE are:

          S -- Include System Files; if S is not present, then
                    ERASE does not "see" System Files

          R -- Erase Read/Only Files without asking the user for
                    permission; if ERASE encounters a Read/Only
                    filσ whilσ i⌠ i≤ performinτ it≤ functioε
                    without the R option enabled, it will ask
                    the user if he wants to erase the file before
                    it does so; with the R option, it simply goes
                    ahead and erases the file

          I -- Inspect; ERASE can be instructed to display each
                    file to the user and ask permission before
                    it erases it; if the user gives permission
                    and ERASE discovers that the file is R/O with
                    the R option off, it will ask a second time
                    before going ahead

Examples:
     ERASE A4:*.TXT      Erase all Non-System files of type
                         TXT in directory A4; if a file is R/O,
                         ERASE will ask for permission before
                         proceeding

     ERASE *.TXT,TXT:*.TXT RI
                         Erase all Non-System files of type TXT
                         in the current directory and in the
                         directory named TXT; if a file is R/O,
                         go ahead and erase it; allow the user to
                         see the name of the file and approve its
                         erasure before it is erased

     ERASE SCRATCH: SR   Erase all System and Non-System files
                         iε thσ director∙ nameΣ SCRATCH╗ iµ ß
                         file is R/O, erase it without asking;
                         this erases absolutely every file in
                         that directory

          . RENAME supports a Control Mode, where the user is
               presented with each file to be RENAMEd and allowed
               to manually enter the new name or not rename the
               file
          . RENAME accepts a list of files
          . RENAME does not "see" System files unless told to
          . RENAME can rename Read/Only files
          . RENAME sets the attibutes (R/O and SYS) of the
               new file names to be the same as those on the
               old file names
          . RENAME supports Named Directories


     The RENAME command is of the general form:

          RENAME dir:f1.typ,dir:f2.typ,... o...

     The options to RENAME are:

          S -- Include System Files
          I -- Allow user to Inspect the file before performing
                    the rename
          C -- (Control Mode) Allow the user to manually name

     RENAME A4:*.MAC=*.ASM,*.TXT=*.TEX IS
          Rename all files of type ASM in A4 to type MAC; also
          rename all files of type TEX in the current directory
          to type TXT; include System files and Inspect (approve)
          each file before the rename is done

     RENAME TXT: C
          Rename all Non-System files in directory TXT; the user

     RENAME 1:*.TXT CS

          Set the Attributes of all COM files in directories A4
          and ROOT to Read/Only and System.  Turn off the Archive
          attribute and all tag bits.  Allow the user to inspect
          each file before the operation is performed.

     PROTECT ROOT:*.TXT
          Clear all attributes and all tag bits of all files of
          type TXT in the directory named ROOT

     PROTECT A: C
          Allow the user to manually set all attributes and tag
          bits of all files on Disk A in the current user

purposes:

          1.  to allow the user to program a wait in a multiple
               command line until he instructs the system to
               continue

          2.  to allow the user to abort a multiple command line

          3.  to allow the user to program an interruptable delay
               in the execution of a multiple command line

          4.  to provide a simple alarm for the user


     The SAK command line is:

          SAK o...

where "o" is zero or more of the following options:

          A    -- DO NOT Allow the User to Abort the MCL
          B    -- Ring Bell

It has no arguments.

     COMMENT has two main applications in the ZCPR2 environment:

          1.  when the console displays are being recorded,
               COMMENT allows the user to easily type notes
               to the future reader without having to begin
               lines with a semicolon (;); all of these lines
               are clearly shown to be comments since they begin
               with the prompt "COMMENT>"

          2«  wheε consolσ I/╧ i≤ redirecteΣ t∩ tw∩ differen⌠
               users, such as CRT and MODEM I/O in parallel,
               then COMMENT may be used to provide a simple
               mechanism for them to communicate; both users
               can type to each other without having any effect
               on the system (such as command processing)
