cygwin is a system that lets you install what programs you want.

What's your shell? I'm assuming BASH until you say otherwise...

Code:
for ((I=1; I<N; I++))
do
        for ((J=1; J<N; J++))
        do
                grep "$i.*$j" maindatafile
        done > outputfile$I
done

I don't think that 'grep' does what you think it does, but you haven't told me what you're trying to match either.
