Just add a newline character to the printf command
Code:
printf "%s\n" SP

Don't forget to do the same for the other printf command between else and fi.
The third printf does not need to be modified.

Hope this will produce the required output.

Thats a fun excercise Smilie

Here is my test to reverse the input as well:
I mean, it has to be able to translate it both ways, doesnt it? Smilie
Code:
+ ~ $ morse "Hello UNIX DOT com"
....;.;.-..;.-..;---;SP;..-;-.;..;-..-;SP;-..;---;-;SP;-.-.;---;--;EOT

:) ~ $ morse "....;.;.-..;.-..;---;SP;..-;-.;..;-..-;SP;-..;---;-;SP;-.-.;---;--;EOT"
HELLO UNIX DOT COM 
EOT

:) ~ $ morse -l "....;.;.-..;.-..;---;SP;..-;-.;..;-..-;SP;-..;---;-;SP;-.-.;---;--;EOT"
HELLO 
UNIX 
DOT 
COM 
EOT
:) ~ $

Show me yours, i'll show you mine Smilie

Thank you kind sir!

I must say - for a novice trying to learn Unix, this board has been a godsend. I continue to be blown away by the number of people willing to help. Not only that, but they're always polite and welcoming toward new members. Thank you!!

Note that i 'had' to change the morse-codes per letter to be without a ;, furthermore it requires now a ; before SP (read: after every letter).
But 'forcing' that, one can switch between 2 output types, all on one line, or each word a seperate line.

Code:
morse "--;.-;-.--;SP-;....;.;SP..-.;---;.-.;-.-.;.;SP-...;.;SP.--;..;-;....;SP-.--;---;..-;EOT"

Code:
morse ".-;-.;-..;SP..;SP....;---;.--.;.;SP-;....;..;...;SP.--;.-;...;SP-.;---;SP....;---;--;.;.--;---;.-.;-.-;EOT"

EDIT:
Bleh, me alrady scripting way too much..
But thanks for the mind break Smilie

The bash utility on the current OS X (GNU bash, version 3.2.53(1)-release (x86_64-apple-darwin14)) does not support associative arrays. With a 1993 or later version of the Korn shell, you could try something like:
Code:
#!/bin/ksh
Morse=( [A]=".-," [B]="-...," [C]="-.-.," [D]="-..," [E]=".," [F]="..-.,"
	[G]="--.," [H]="....," [I]="..," [J]=".---," [K]="-.-," [L]=".-..,"
	[M]="--," [N]="-.," ["O"]="---," [P]=".--.," [Q]="--.-," [R]="--.-,"
	[S]="...," [T]="-," [U]="..-," [V]="...-," [W]=".--," [X]="-..-,"
	[Y]="-.--," [Z]="--..," [0]="-----," [1]=".----," [2]="..---,"
	[3]="...--," [4]="....-," [5]=".....," [6]="-....," [7]="--...,"
	[8]="---..," [9]="----.," [ ]="SP," [.]="STOP," )

while [ $# -gt 0 ]
do	arg="$1"
	for (( i = 0; i < ${#arg}; i++ ))
	do	printf '%s' "${Morse["${arg:i:1}"]}"
	done
	[ $# = 1 ] && printf 'EOT\n' || printf '%s' "${Morse[ ]}"
	shift
done

which could be invoked as:
Code:
./morse.ksh SOS "1 2 3" "THIS IS A TEST."

to produce the output:
Code:
...,---,...,SP,.----,SP,..---,SP,...--,SP,-,....,..,...,SP,..,...,SP,.-,SP,-,.,...,-,STOP,EOT
