    shift
    case "$CHOSEN_KEY" in
       1) echo TEST1 ;;
          if [ $CHOSEN_KEY -eq 1 ];
          echo TEST1 ;;
          then
          echo "Select Version"
          echo "[a] - Version 6"
          echo "[b] - Version 7"
          echo "Please enter your option: "
          read "CHOSEN_VER"
          if [ "$CHOSEN_VER" == "a" ];
          then
          echo " You have chosen Version 6 installation "
          elif [ "$CHOSEN_VER" == "b" ];
          then
          echo " You have chosen Version 7 installation "
          else
          echo "Select proper category"
          fi
          fi
          break;;

There are several problems here. Note the code marked in red above.

First the 1st ";;" on the first line of the actions for case 1 terminates the actions for that case. Having an if statement following that is not allowed. I assume you should just remove this ";;".

Second, you are in the actions to be performed when $CHOSEN_KEY expands to 1; so why do you need to test whether $CHOSEN_KEY still expands to 1 one line later?

Third, you have an echo statement after an if statement before the then keyword. And, it ends with another ";;".

I'm guessing you want something more like:
Code:
while [ $# -ge 1 ]
do
    CHOSEN_KEY="$1"
    shift
    case "$CHOSEN_KEY" in
    (1) echo TEST1
        echo 'Select Version'
        echo '[a] - Version 6'
        echo '[b] - Version 7'
        printf 'Please enter your option: '
        read CHOSEN_VER
        if [ "$CHOSEN_VER" = "a" ]
        then
            echo ' You have chosen Version 6 installation'
        elif [ "$CHOSEN_VER" = "b" ]
        then
            echo ' You have chosen Version 7 installation'
        else
            echo 'Select proper category'
            # I am surprised that you do not exit here instead of continuing???
        fi
        break;;

platform::shell

platform::shell(3tcl)					       Tcl Bundled Packages					     platform::shell(3tcl)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
