help with script parameter checking based on environment

I need to check if the parameters are correctly passed based on the Environment I am in.

For e.g when I am in dev the 1st paramter needs to be either A OR B OR C OR D
similarly when I am in qa the parameter needs to be either e or f

so i need to write a case staement or a if statement to acheive this

I wrote a case statement as below. SIEBELENV is an environment variable from the .profile

Code:

case $SIEBELENV in
        DEV)       SERVER_PATH="A|B|C|D" ;;
        QA)        SERVER_PATH="E|F" ;;
        *)    echo "$(date). Invalid ENV variable $SIEBELENV. Please check environment variable file." >> $LOG_FILE
                    rc=2
                    return $rc
                    exit ;;
esac

I have set the paths correctly based on the enviroment. but I need to make sure when the script runs in dev with a parameter equal to any of the FTP paths set for dev from case statment then only proceed
otherwise send an mail saying wrong parameters based on environment.

for e.g script would be called like this interface.ksh A g4 ( A is the SERVER_PATH ). I need to see if this is running in dev it should accept only either A or B orc or D

Otherwise throw an error that environment and paramter doesn't match

How can I do this

atf-sh

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME

     atf-sh [-s shell] -- interpreter for shell-based test programs

SYNOPSIS

     atf-sh script

DESCRIPTION

     atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.

     atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL.  atf-sh executes the inter-
     preter, loads the atf-sh(3) library and then runs the script.  You must consider atf-sh to be a POSIX shell by default and thus should not
     use any non-standard extensions.

     The following options are available:

     -s shell	  Specifies the shell to use instead of the value provided by ATF_SHELL.

ENVIRONMENT

     ATF_LIBEXECDIR    Overrides the builtin directory where atf-sh is located.  Should not be overridden other than for testing purposes.
     ATF_PKGDATADIR    Overrides the builtin directory where libatf-sh.subr is located.  Should not be overridden other than for testing purposes.
     ATF_SHELL	       Path to the system shell to be used in the generated scripts.  Scripts must not rely on this variable being set to select a
		       specific interpreter.

EXAMPLES

     Scripts using atf-sh(3) should start with:

	   #! /usr/bin/env atf-sh

     Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh.  Instead, you have to hardcode
     the path to atf-sh in the script and then use the -s option afterwards as a single parameter:

	   #! /path/to/bin/atf-sh -s/bin/bash

ENVIRONMENT

     ATF_SHELL	  Path to the system shell to be used in the generated scripts.
