Here I changed it to $abbrev{$line} = $abbre;

OUTPUT:
%abbrev = (
'CNS Neurol Disord Drug Targets' => 'CNSNDDT',
'Intermolecular Forces' => 'IF',
'Expert Reviews in Molecular Medicine.' => 'ERMM',
'Nat. Neurosci.' => 'NN',
'Nat. Rev. Mol. Cell Biol.' => 'NRMCB',
'Nature Cell Biol.' => 'NCB'
);
My question is that how can I sort the values. I googled for a while.
sort $abbrev{$a} cmp $abbrev{$b} it complains that:
name "main::b" used only once: possible typo at try.pl line 24.
Name "main::a" used only once: possible typo at try.pl line 24.
Use of uninitialized value $a in hash element at try.pl line 24,
<$_[...]> line 6.
Use of uninitialized value $b in hash element at try.pl line 24,
<$_[...]> line 6.
Use of uninitialized value in string comparison (cmp) at try.pl line
24, <$_[...]> line 6.
Use of uninitialized value in string comparison (cmp) at try.pl line
24, <$_[...]> line 6.
Use of uninitialized value in concatenation (.) or string at
Thanks again,
