I have mathematica 10 and a currently working to shift a large Hypercard database into Mathematica. Many questions that I'll be asking are quite basic to Mathematica.

Here is the information contained in one card (there are > 16,000) along with metadata about the card

Total Number of Cards = 1 Begin card "X1766697" card id 1897041 Nature vol. 316 p 457 - 460 '85 4 "Choroid plexus tumors" 1711804 Xref "SV40" 1433061 glossary "SV40 -- moreInfo" 2104481 Xref "Transgenic animals" 1512732 "glossary" 1 Oncogenes 1 Transgenic mice with SV40 early genes die of choroid plexus papillomas at age 3 -5 months. Elevated SV40 T antigen and SV40 mRNA are present in affected tissues. If the SV40 enhancer region is deleted, there is peripheral neuropathy rather than choroid plexus tumors, and there are liver and pancreatic tumors as well.

I'm interested in opinions about upgrading to Mathematica 12
