Re^7: filtering an array

[philiprbrenan]

One or more of the elements of the array @positions is undefined. The easiest way to check this is like this:

use Data::Dump qw(pp);

pp([@positions]);

This will give you a printout of the value of each element in array @positions. I expect we will see that some are "undef" meaning undefined. It will be these elements that are causing the problem.

i don't see any that are "undef. that's a little strange. the data dumper output prints:

9031,

"A"

etc. etc. this is a little strange...
