Hi I want to take out an entire row of a multidim array (everything
about it) and have the row below "assume" the row and index numbers
(and any other subsequent rows also would move up 1 with their
indices)..

Also, I am looking for a good way to count the number of rows in a
given multidim array..

Curious how this can be done.

Thank you,

Jack
