I think you might want to use "exists" instead of "defined" in this case, or
maybe both depending on what you are trying to do.
$addr4=$abbrevs{$addr4}
if (exists $abbrevs{$addr4} and defined $abbrevs{$addr4});

Subject: unexpected runtime error
Hi folks,
I'm getting:
Use of uninitialized value in hash element at /home/gary/bin/svcimport line
188, <FIN> line 4301.
when running my program, of which like 188 is:
$addr4=$abbrevs{$addr4} if (defined $abbrevs{$addr4}); # expand
abbreviations
Surely the 'if defined' should prevent this from happening by checking that
it
is in fact initialized. BTW, I'm not getting it for every input line, but
for a significant number.
