No you hadn't, you were using four inefficient externals to do that, but to split one string, use the substring operator:
Code:
echo ${B:0:1}

See String Operations

Here is another approach using awk:-
Code:
echo "192.168.1.1" | awk -F'.' '
        {
                for ( i = 1; i <= NF; i++ )
                {
                        for ( j = 1; j <= length($i); j++ )
                        {
                                A_oct[i OFS j] = sprintf ( "%d", substr( $i, j, 1 ) )
                                A_max[i] = j
                        }
                }
        }
        END {
                for ( i = 1; i <= NF; i++ )
                {
                        print "Octet:", i
                        for ( j = 1; j <= A_max[i]; j++ )
                        {
                                print A_oct[i OFS j]
                        }
                }
        }
'

Produces output:-
Code:
Octet: 1
1
9
2
Octet: 2
1
6
8
Octet: 3
1
Octet: 4
1

Then you're not really in BASH.

ksh has it too, but only modern ksh, not ksh88.
