Positional Parameters

HPUX11.0/Korn Shell
I have an old script that takes in a series of arguments when its called. The script is really more of a common set of functions that gets called by other scripts as needed. I have been asked to make this into a menu driven script to rollout to app support for their use during support calls. The script currently uses getopts to evaluate and check the arguments passed to it. I want to add at most 2 menus but I dont want to have to rewrite the getopts and checksum. The script accepts arguments in the form: -s arg, -t arg -u arg etc. Is there a way to set the positional arguments $1, $2 , $3 from within the script (after the script has been executed) so that I can just plug in the menu without a lot of rework? Trying to save some time. Thanks for any and all responses and suggestions.

execute script (no args) --> display menu --> read choice --> display usage --> accept arguments from user --> pass to getopts function that is already written --> process request.

SHCOMP(1)						       Korn shell utilities							 SHCOMP(1)

NAME
shcomp - compile a shell script SYNOPSIS
shcomp [ options ] [infile [outfile]] DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with the same effect as the original script. Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly. If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to locale specific versions for internationalization. If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from standard input. OPTIONS
[D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization. [n noexec] Displays warn- ing messages for obsolete or non-conforming constructs. [v verbose] Displays input from infile onto standard error as it reads it. EXIT STATUS
0 Successful completion. >0 An error occurred. SEE ALSO
