Array not printing values if used in a loop
Hello!

I'm making an English to Morse Code translator and I was able to mostly get it all working by looking through older posts here; however, I have one small problem.

When I run it it's just printing spaces for where the characters should be. It runs the right amount of times, and if I try to individually print out of the array it works, but when I try to have it cycle through to translate I get the problem.

What I am running/output:
Code:
[acolem26@ats-cis project8]$ ./morse "a b c"
 SP  SP  EOT

My code:
Code:
#!/bash/bin

declare -A code
code[A]=".-"
code[B]="-..."
code[C]="-.-."
code[D]="-.."
code[E]="."
code[F]="..-."
code[G]="--."
code[H]="...."
code[I]=".."
code[J]=".---"
code[K]="-.-"
code[L]=".-.."
code[M]="--"
code[N]="-."
code[O]="---"
code[P]=".--."
code[Q]="--.-"
code[R]=".-."
code[S]="..."
code[T]="-"
code[U]="..-"
code[V]="...-"
code[W]=".--"
code[X]="-..-"
code[Y]="-.--"
code[Z]="--.."
code[1]=".----"
code[2]="..---"
code[3]="...--"
code[4]="....-"
code[5]="....."
code[6]="-...."
code[7]="--..."
code[8]="---.."
code[9]="----."
code[0]="-----"
code[ ]="SP"

str=$1

for (( i=0; $i < ${#str}; i++ ));
do
     printf "%s " "${code[${str:$i:1}]}"
done
printf "%s\n" EOT

If I do something like

Code:
printf "%s " "${code[A]}"

It prints off the corresponding Morse code so I assume the issue isn't with the array but with how I am substituting and I'm not sure how to fix it.

NAME

       CW - the international Morse code

DESCRIPTION

       CW  is  an  abbreviation for "continuous wave", the commonly used technical term for Morse code communication.  A basic knowledge or under-
       standing of Morse code is a requirement for Radio Amateurs and Marine Radio Operators in many parts of the world.

   MORSE CODE TIMINGS
       In Morse code, a dot or dash is referred to as an element.  The basic timing unit is the dot period.  This is the time taken to send a dot,
       not  including  any space before or after the dot.  The lengths of all other elements are then derived from this basic unit, using the fol-
       lowing rules:

	      The duration of a dash is three dots.

	      The time between each element (dot or dash) is one dot length.

	      The space between characters is three dot lengths.

	      The space between words is seven dot lengths.

       The following formula calculates the dot period in microseconds from the Morse code speed in words per minute:

	      dot period = ( 1200000 / speed )

       This formula arises from the use of the word PARIS as a 'standard' word for calibrating Morse code speed.  PARIS is 50 units long when sent
       in Morse code.  Analysis of English plain-text indicates that the average word is 50 units, including spaces.

   MORSE CODE CHARACTERS
       The following list shows the IS0 8859-1 (Latin-1) characters that have commonly understood representations in Morse code:

	      ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"$()+-./:;=?_@ and space

       In addition, following ISO 8859-1 and ISO 8859-2 accented characters are also part of the generally accepted international Morse code:

	      UACOEEANS (S with cedilla),  (Z with caron/hacek),

       Finally, libcw adds the following ASCII characters as extensions to single character procedural signals:

	      <>!&^~

   MORSE CODE CHARACTER TABLES
       The  following  table  shows  the Morse code equivalents for the ISO 8859-1, accented ISO 8859-1, and accented ISO 8859-2 characters above.
       The ASCII portion of this table is taken from the ARRL Handbook, and the accented extensions from various other sources:

       Ch   Code     Ch   Code	   Ch	Code	  Ch   Code
       -------------------------------------------------------
       A    .-	     B	  -...	   C	-.-.	  D    -..
       E    .	     F	  ..-.	   G	--.	  H    ....

       8    ---..    9	  ----.

       )    -.--.-   +	  .-.-.    ,	--..--	  -    -....-
       .    .-.-.-   /	  -..-.    :	---...	  ;    -.-.-.

       =    -...-    ?	  ..--..   _	..--.-

       Ch	       Code    Ch		  Code
       -------------------------------------------------
       U	       ..--    A		  .-.-
       C	       -.-..   O		  ---.
       E	       ..-..   A		  .-..-
       A	       .--.-   N		  --.--
       S (S+cedilla)   ----	(Z+caron/hacek)   --..-

       In addition to the above standard characters, the following characters are conventionally used for punctuation and  procedural  signals	as
       follows:

       Ch   Code     Ch   Code	   Ch	Code	  Ch   Code
       -------------------------------------------------------
       "    .-..-.   '	  .----.   $	...-..-   (    -.--.
       )    -.--.-   +	  .-.-.    ,	--..--	  -    -....-
       .    .-.-.-   /	  -..-.    :	---...	  ;    -.-.-.
       =    -...-    ?	  ..--..   _	..--.-	  @    .--.-.

       and the following are non-conventional extensions implemented by libcw:

       Ch   Code     Ch   Code	    Ch	 Code	 Ch   Code
       -----------------------------------------------------
       <    ...-.-   >	  -...-.-   !	 ...-.	 &    .-...
       ^    -.-.-    ~	  .-.-..

       An alternative view of punctuation and procedural signals is as combination Morse characters:

       Ch   Prosig	Ch   Prosig   Ch   Prosig   Ch	 Prosig
       ---------------------------------------------------------
       "    [AF]	'    [WG]     $    [SX]     (	 [KN]
       )    [KK]	+    [AR]     ,    [MIM]    -	 [DU]
       .    [AAA]	/    [DN]     :    [OS]     ;	 [KR]
       =    [BT]	?    [IMI]    _    [IQ]     @	 [AC]
       <    [VA],[SK]	>    [BK]     !    [SN]     &	 [AS]
       ^    [KA]	~    [AL]

NOTES

       Despite	the fact that this manual page constantly and consistently refers to Morse code elements as dots and dashes, DO NOT think in these
       terms when trying to learn Morse code.  Always think of them as 'dit's and 'dah's.
