This is right but you can pad by adding zeroes at the begin and then get the characters one at a time from right to left until you hit zero:

Code:
NUM=1
# NUM=12
# NUM=123

XNUM="00$NUM"

echo ${XNUM#${XNUM%?}}      # rightmost char
...etc.

(caution: not tested with a real Bourne shell as i do not have such a thing)

(addendum: if you use ksh (any ksh) you can typeset -RZ3 the variable and don't need the padding)

I hope this helps.
