Did you try the man pages ? They are a very good source of information.
man sh says
Code:
              --      If no arguments follow this option, then  the  positional
                      parameters  are unset.  Otherwise, the positional parame-
                      ters are set to the args, even if some of them begin with
                      a -.

See this

Code:
[/tmp]$ cat try.sh
#! /bin/sh

arg="first second third"

if [ $# -eq 3 ] ; then
    echo $1
    echo $2
    echo $3
fi;

set -- $arg
echo $1
echo $2
echo $3
[/tmp]$ ./try.sh 12 23 34
12
23
34
first
second
third
[/tmp]$ ./try.sh
first
second
third
[/tmp]$

NAME
dbfdump - Dump the record of the dbf file FORMAT
dbfdump [options] files where options are --rs output record separator (default newline) --fs output field separator (default colon) --fields comma separated list of fields to print (default all) --undef string to print for NULL values (default empty) --memofile specifies unstandard name of attached memo file --memosep separator for dBase III dbt's (default x1ax1a) --nomemo do not try to read the memo (dbt/fpt) file --info print info about the file and fields with additional --SQL parameter, outputs the SQL create table --version print version of the XBase library --table output in nice table format (only available when Data::ShowTable is installed, overrides rs and fs) SYNOPSIS
dbfdump -fields id,msg table.dbf dbfdump -fs=' : ' table dbfdump --nomemo file.dbf ssh user@host 'cat file.dbf.gz' | gunzip - | dbfdump - DESCRIPTION
Dbfdump prints to standard output the content of dbf files listed. By default, it prints all fields, separated by colons, one record on a line. The output record and column separators can be changed by switches on the command line. You can also ask only for some fields to be printed. The content of associated memo files (dbf, fpt) is printed for memo fields, unless you use the "--nomemo" option. You can specify reading the standard input by putting dash (-) instead of file name.
