in reply to Getting table dimensions

You say: 
my $tableDimensions = @$futureTable;
my $numRows = $tableDimensions->[0];

[download]
Assuming that $futureTable is an arrayref, then $tableDimensions contains the number of elements in that array, an integer. So what do you expect to happen when you dereference an integer?

    I knew it was something silly I was overlooking. Thanks.

    If you give a man a fish he will eat for a day.
    If you teach a man to fish he will buy an ugly hat.
    If you talk about fish to a starving man, you're a consultant.
