Line 11 treats the result of "split" as a list of "key => value" pairs. You
end up with something like this...
$fieldMap{8} = 1023240136
$fieldMap{1218} = 0
$fieldMap{1} ="00a000001a2bcdc7"
Perl expects the data to have a value for every key. The first error - odd
number of elements - means that Perl saw a key without a corresponding
value. The data has an odd number of elements. To save into a hash, it
should have an even number of elements.
