Thanks!
The script returns an error msg:
Global symbol "$f500" requires explicit package name at s.pl line ###
Execution of s.pl aborted due to compilation errors.
The $f500 was deleted in the earlier loop. Was that the cause?
BTW, was there a difference between the close curly bracket with
or
In your foreach loop, you write a new 534 for every 500 that you find. The
first one has the subfield a from it, the 2nd one has a subfield a from the
first and second, etc. What you really want to do is something like:
if (@f500s) {
my @subfields = ();
foreach my $f500 (@f500s) {
$f500->
