Re^2: comparison of two hashes

Thanks a BUNCH! This helps a lot! Just one more small help from you, i am not sure i fully understand what this portion does:

my $file1 = <<EOF;
Cell: AND1
A1 A2 Y
Cell: INV1
A Z
EOF

my $file2 = <<EOF;
Cell: AND1
A B Y
Cell: INV2
A Z
EOF

The `<<EOF` syntax is known as a "here-doc", which you can read about in Quote and Quote like Operators. I use it here to assign a multi-line string to a scalar variable. This was a convenient way for me to create a completely self-contained example which you could just copy-n-paste and run, without having to create 2 extra, external data files. Of course, in your application, you would read your 2 input files into your script.	[reply] [d/l]
