You're doing a bit more work than is needed by using sed and wc; Kshell can do that easily and more efficiently than invoking external processes. Here's an example which does pretty much what you are looking for:

Code:
#!/usr/bin/env ksh

id="${1//\"/}"              # no need to pipe it through sed to strip quotes
option="${2//\"/}"
shift 2
typeset -a server=( $* )   # capture remaining parms into the server list
total_server=${#server[*]}  # no need to pipe it through wc to count; this generates size of the array 
for (( i = 0; i < $total_server; i++ ))
do
    typeset -u server_upper[$i]=${server[$i]}
done

typeset -u option_upper="$option"
typeset -u id_upper="$id"
echo "$option  $option_upper"
echo "$id $id_upper"
echo "$total_server"
echo "${server[0]}"
echo "${server_upper[0]}"
exit

If you are stripping the quotes because someone might enter the command like this:
Code:
command "parm1" "parm2" "server1 server2 server3"

Then you don't need to worry about the quotes -- Kshell will do the right thing and the quotes will be removed by the shell. The example above handles the server list as shown or as
Code:
command p1 p2 server1 server2 server3

(as single tokens, or one quoted token list). It should also handle n servers.

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
           able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
           performed.
