not the most efficient way but it works in showing user input with case statement.

Code:

#!/bin/bash

y=1
echo -e "Choose Names as listed in the format below.\n \
1. mango\t2. tango\t3. rango\t4. exit"
read answer


while [ $y=1 ]; do
    case ${answer} in
    "[Mm][Aa][Nn][Gg][Oo]"|1)
        echo "mango"
        mode="mango"
        echo -e "Specify an Option\n1. add\t2. sub\t3. exit"
        read option
        case ${option} in
            "[Aa][Dd][Dd]"|1)
                echo "you chose add"
                ;;
            "[Ss][Uu][Bb]"|2)
                echo "you chose sub"
                ;;
            "[Ee][Xx][Ii][Tt]"|3)
                echo "goodbye"
                exit 0
                ;;
        esac
        ;;
    "[Tt][Aa][Nn][Gg][Oo]"|2)
        echo "tango"
        mode="tango"
            echo -e "Specify an Option\n1. add\t2. sub\t3. exit"
            read option
            case ${option} in
                    "[Aa][Dd][Dd]"|1)
                            echo "you chose add"

echo(3XCURSES)						  X/Open Curses Library Functions					    echo(3XCURSES)

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int echo(void);

       int noecho(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.

RETURN VALUES

       Upon successful completion, these functions return OK. Otherwise, they return ERR.

ERRORS

       No errors are defined.
