New book on Mumps & Cache
rtweed
Mumps & Cache, I've learned that Mike (Paul) Kadow has published a new
book: Cache ObjectScript & Mumps. I knew he had been close to getting
it published, so it's good to hear that he's finally got it out: a
huge effort on his part, for which he should be congratulated.
It covers both "traditional" Mumps and the newer Cache-specific
extensions, so it's ideal for anyone wanting to understand the
potential differences in VistA etc that you'll see on either Cache
systems (eg at the VA) or on GT.M systems. It also provides a more
modern take on the practice of using the Mumps language than we've
seen in the past. I'd say it's worth a look.

response the the equivalent question in the Cache & Ensemble Google
Group:
"no the book is not available as an e-book.
I barely got it out as I did, you would not believe what it takes,
perhaps
in time I can make it available as an e-book.
