That makes sense, it lowers the bar to jump into externalizing I/O. I guess I just don't consider it very modern. The introduction to the database design got a lot friendlier in the last 16 years.

Old

"The initial database design

Our initial database doesn't really deserve the term "design". It is a System/36

style flat file with multiple record types. Sound familiar?"


New

"The initial database design

The initial database design is a misnomer. It is a System/36 style flat file with multiple record

Jon, what part of the new draft did you elaborate?

Not going to comment on the SQL/GOTO bit - haven’t read that and I hate SQL’s pathetic error handling to begin with.

But … DDS is to be expected. It is after all a book about what you _should_ be doing - if there are no points of reference for those who have not yet made the jump …

Sneaky Redbooks, trying to get their GOTO statements back using the SQL whenever statement.

No, seriously, isn't including those kind of jumps in your code a really bad idea? It's on page 180 of the Redbook by the way.

I was also a bit surprised to see a DDS file definition. But it's fantastic to see a re-vamp of this Redbook!

Ah, so the errors are a deliberate ploy by the author(s) to make the
reader learn more. Clever. ;)

Ironically, one of the worst books I ever remember trying to learn from was
a book on Python.

Worst because it was TOO copy-pastable, or because it had too many
errors, or because it just didn't explain things well?

If I may ask, do you remember which book it was?
