in reply to Push array into array of arrays

With push (@myArrofArray, \@myArray); you are adding a reference to @myArray to @myArrofArray. Printing Array references looks like ARRAY(0x7c8f60), but the number in parentheses will be different every time.

If you want to unfold the individual elements of @myArray into @myArrofArray, use:

push (@myArrofArray, @myArray);

If you want to print individual elements of @a, unfold the elements before pushing them:

push(@a,@{pop(@myArrofArray)});
