While I was  developing a small script,  I thought about how to use -N flag to a greater extent. Although  -N in its own is very limited. It does serve the purpose but not what I need.  I also discussed this in #bash freenode,  and got some ideas like:

pgas:   while read -n1 d;do case $d in '')break;;  [0-9])var+=$d;;*) echo error;;esac;done

A for loop is probably not such a bad idea either. I'll try and see if I can figure out something.

Any reason to justify this instead of using a simple loop?
