Okay thanks for your help thus far. Ill sleep over it and see if i can make changes. Possibly ill start again and use case instead. Ill be on tomorrow.

---------- Post updated at 04:00 PM ---------- Previous update was at 12:19 AM ----------

Ive been working on the code and this is what i get so far. Everything works ok it accepts inputs one at a time. However when i want to exit (by pressing 0 and enter) i need to do it twice and it makes 0 the lowest letter. Its not what i want and im sure in the code i made it so it would exit out right after 0 was found and to display the lowest letter.

Code:
"3")
clear
echo Enter capitol alphabetical letters one at a time and press 0 to finish
letter="Z"
if [[ "$letter" < Z || "$letter" == Z ]] && [[ "$letter" > A || "$letter" == A ]] || [[ "$letter2" == 0 ]]; then
        while [[ "$letter" == Z || "$letter" < Z ]] && [[ "$letter" > A || "$letter" == A ]] || [[ "$letter2" == 0 ]]; do
        letter2="Z"
        read letter2
                if [[ "$letter2" < "$letter" ]]; then
                letter=$letter2
                elif [[ "$letter2" == 0 ]]; then
                echo Lowest Letter is $letter
                echo Press enter to continue...
                elif [[ "$letter2" == "$letter" ]]; then
                letter=$letter2
                elif [[ "$letter2" > "$letter" ]]; then
                read letter2
                else
                echo "Invalid Input. Please enter A-Z one at a time finalised by a 0"
                fi

        done
else
echo "Invalid input. Please enter A-Z (capital) one at a time finalised by a 0"
fi
;;

RE(1)							      General Commands Manual							     RE(1)

NAME

       re - programm to conver russian texts between different encodings

SYNOPSIS

       re <infile><outfile><infrmt><outfrmt><f|b|s><u|l|s>

DESCRIPTION

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

       re is a program that converts russian texts between encodings.

OPTIONS

       The easiest way to convert some file into readable form (KOI-8), just type this:

       re <SourceFile> <DestFile> ? K

       where :

       <SourceFile> - unreadable file

       <DestFile>   - resulting file

       ?	    - tells RE that source codepage is unknown and RE should analyze the file and determine the source codepage

       K	    - tells RE that destination codepage is KOI-8

       Note:  If  you  know, what is source codepage, you may use it instead of "?" option. For example, you want to convert letter.txt file which
       was written in Win you know, that this file is in 1251 codepage:

	   re letter.txt letter2.txt W K

       Now examine the letter2.txt - you should see russian symbols in KOI-8.

       Here is the know codepages list and their abbreviatures:
	   W   - Windows 1251	 "_"  - _xxe
	   D   - Dos		 "%"  - %hex
	   K   - KOI-8		 "\" - 'hex
	   L   - Latin		  G   - Graph_win
	   I   - Iso		 "<"  - <binhex>
	   H   - HEX		  +   - +UTF7-
	   S   - ShiftKbrd	  C   - C_MIC
	   M   - Mac		  Y   - Y_c16
	   A   - AFF		  Z   - Z_c32
	   O   - Odd(UTF8_1)	  F   - F(UTF8_2)
	   B   - Base64 	  P   - Pict
	   E   - Express	  N   - N_Estl
	   T   - T-Html 	  V   - V_Vpp855
	   U   - User		  X   - X_sp
	   "-" - uue		  J   - J_diff

       Other options are: [-v][-E|-R|-N][-e|-s]
	    -v - tells what is processing
	    -n - don't tells what is processing (default)
	    -E - converts all p,H from Russian to English
	    -R - converts all p,H from English to Russian
	    -N - lets all p,H Russian or English as in text (default)
	    -e - converts all symbols 0x80 - 0xFF
	    -s - converts only 64 symbols of Russian Alphabet (default)
