I was using a hash to accumulate occurrences of a string (jobnames) in the file and I
tried to use ++ to auto increment; but it didn't work. Since TMTOWTDI, I found an
easy solution but I'm just curious as to why this doesn't work. Shouldn't the value
of key 'A' be 2?; why doesn't ++ work or what did I do wrong?
TIA

use strict;
my %hash;
$hash{'A'} = '0';
#why doesn't this work...
$hash{'A'} = $hash{'A'}++;
#isn't it logically equivalent to this?
$hash{'A'} = $hash{'A'}+1;
print "VALUE of A:$hash{'A'}\n";
_END SNIPPET_
