I know it's a reference to a hash. What I don't know is why it's printing
out like this. I have hash values that I need to print out, but not in any
order, so I put each hash value that I want to print in a join statement in
the order I need them. The really strange part is that I also have a print
statement to help me debug my code, and I print out each hash value. I
commented out each part that printed a hash value to the screen, and only
left the phrase:
print "Printing hash values: \n";
When it printed, it still printed out a hash reference, like this:
From the GetHdrLine function:
HASH(0x1c6ed80)From the GetHdrLine function:
HASH(0x1ab5300)From the GetHdrLine function:
HASH(0x1c6eda4)From the GetHdrLine function:
HASH(0x1ab52d0)From the GetHdrLine function:
HASH(0x1ab5390)From the GetHdrLine function:
HASH(0x1ab5330)From the GetHdrLine function:
HASH(0x1cbe35c)From the GetHdrLine function:
Why would it do that? Maybe I'm not being clear, so I can post code if it
would be more helpful.
I don't think I completely understand your code. When you put
'join( '|', values %hash )'
what exactly do you mean? Should I put each hash value that I'm wanting to
print, and then the word %hash? That doesn't seem to make any sense to me.
I checked out perldoc perlref, but didn't see anything that pertains to
joins, but maybe I'm missing something. I'm really grateful for your help,
but could you be a bit more specific? I'd appreciate it. Thanks.

This is a reference to a hash.
