Hi RudiC...
You are a star, works with spaces and in this test case too.
Code:
#!/bin/bash

# Only 14 elements here.
printf "ABCDEFGHIJKLMN" > /tmp/ARRAY

IFS="" read TMP < /tmp/ARRAY 
for ((i=0; i<${#TMP}; i++))
do
	ARRAY[${#ARRAY[@]}]=${TMP:i:1}
done

# Note that array element 14 and above should be nothing followed by a number.
for n in {0..15}
do
	printf "${ARRAY[$n]}$n\n"
done

Results...
Code:

Perfect...
This bit is clever, (love it) ARRAY[${#ARRAY[@]}] .
It took me a short while to understand it, but I got there in the end...

Many thanks...

NAME

       CPANPLUS::Shell

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
