Re: Making a hash of arrays using references (push)

Welcome to the monastery Tmms,

Looks like each time you are overwriting the hash entry with a new one element array.

Please try to push instead

push @{$hash{$affiliation}}, $name;

~~Depending on the Perl version you'd be allowed to leave the @{...} out.~~ °

HTH :)

°) please forget, because (strangely) "Starting with Perl 5.14, an experimental feature allowed push to take a scalar expression. This experiment has been deemed unsuccessful, and was removed as of Perl 5.24."
