in thread Variable number of foreach loops

thanks a lot. yes i get it now. In the same light.....i want to call nfor() with different number of arguments...

nfor(1,\@a_1); nfor(2,\@a_1,\@a_2); nfor(3,\@a_1,\@a_2,\@a_3);...so on nfor(N,\@a_1,\@a_2,...\@a_N).
I have a way...but what to check if there is a much crispier way to do it.

    If you store your arrays (more specifically references to your arrays) in an array, you can say

    my @arrayOfArrays = ( \@a_1,\@a_2,...,\@a_20 ); my $n = 10; nfor( $n, @arrayOfArrays[ 0..$n-1 ] );

    Where will you get the variable number of arrays from? And how will you be storing them?

      I have stored my data in N arrays. N varies from 1..20 I have a random string, that i breakdown into some N-segments. Each Segment is then a array. Now i want to run nfor() on these. So as you can see segment size is random. Hence variable number of arrays.

        That's not very clear. Could you post a little code to show me what you mean?

        For example, if you have code like this:

        my( @a, @b, @c ); ## stuff here to fill the arrays

        What happens if you need another array @d?
