in thread Creating and Accessing 3-D array

Yes, I figured out my mistake.

Autovivification is great tool. I did it that way (lazy me :-))

In my opinion, autovivification should not be taught to a beginner. It makes creating multidimentional arrays so simple that, lazy people like me will never study data structures chapter .. :-)

Thanks

    The equivalent without autovivification of the snippet using autovivification is 

    ( ( $sheets[$sheet] //= [] )->[$row] //= [] )->[$col] = 0;

    Your choice.
