                                    EXAMPLES

        LIST FILES IN A NICE FORMAT ON THE SCREEN

        Build a submit file with the following command.  It will put out
        a  very  nice  5  column list of filenames sorted verticaly.  No
        arguments will give a list of all files.  A wild  card  argument
        will  give  a  limited display like DIR.  a second argument will
        allow the output to be sent to a file or the printer.

                LS $1 |2UP -L22N5W $2

        PRINT A TEXT FILE WITH A LEFT MARGIN FOR 3-HOLE PUNCHING

                PAGE <file -M10 >lst:

        BUILDING SUBMIT FILES

        The  following  sequence  will  create a file CLEAN.SUB which is
        a submit job to clean control characters out  of  all  files  of
        type xxx.

                LS *.xxx |SUB * CLEAN_<*_>* >CLEAN.SUB

        A BACKUP SUBMIT FILE BUILDER

        The  following  sequence  will create  a  file  BACKUP.SUB which
        is  a submit job to backup all files of type xxx from disk A: to
        disk B:.

                LS *.xxx |SUB * COPY_B:*_=A:* >BACKUP.SUB

        Either of the above sequences were themselves placed in  a  .SUB
        file.  Thus, if the file BLDBKUP.SUB contained:

                LS *.$1 |SUB * COPY_B:*_=A:* >BACKUP.SUB

        Then the command:

                SUBMIT BLDBKUP BAS

        would create the file BACKUP.SUB to backup  all  .BAS  files and
        the command

                SUBMIT BACKUP

        would execute that function.



















        CREATING AN INDEX FROM A DOCUMENT FILE

        The  following commands in a submit file would allow an index to
        be  built  for  any  text   file   by  use  of  a  single submit
        command.

         WORDS <$1 -NL66 |SORT -C9U |MERGE -C9UI NOISE.WRD >$TEMP$
         INDEX -C29 <$TEMP$ |2UP -M10L60C29S2 |PAGE >INDEX.DOC
         ERA $TEMP$

        Which would be called by:

                SUBMIT INDEX filename

        This  would  create  an index based on  66  line  pages  of  the
        named  file.  The index would be formatted in  2  columns spaced
        out  on  a  66  line  page  format.  The index would contain all
        words in the text except those contained in  the NOISE.WRD  file
        which contains "noise words" such as "the", "and", etc.

        Create the NOISE.WRD file from a  text   file   containing  just
        noise words by:

                WORDS <NOISE.TXT -N |SORT -C9U >NOISE.WRD

        The   same   submit  file  can be modified by changing the "L66"
        after WORDS  to  "L1"  and  would   give   a   cross   reference
        instead.

        ANOTHER TYPE OF BACKUP STRATEGY

        If  you  use  an  editor  which creates .BAK files types for any
        file  modified,  you can use this as  a  signal  to  select  out
        files for backing up.  The following submit file can  be used.

                LS *.BAK |SUB { COPY_B:=A: |SUB .BAK .* >BKUP.SUB
                ERA *.BAK

        This   creates  a  file  BKUP.SUB to backup to disk B: all files
        named the same as the .BAK file.


























        BRACE CHECKING IN C PROGRAMS

        A common problem in C programs is having unmatched {   }  pairs.
        These   are   difficult  to  locate  and a simple search for one
        character in an editor or with SELECT  will  not  do  the   job.
        The   following   submit  commands  will  find and display lines
        containing either bracket along with the  line number  for  that
        line.

                SUB <$1.C \} \{\}\{ |SELECT \{ -N |SUB \{\}\{ \} $2

        The   $2   argument   allows   the  default  output to be to the
        screen, but the output can  be   redirected   to   the   printer
        (>LST:) or a file.
