1. The Future of Paradox Blog

If you have an existing Paradox system you can keep using it but you'll need to skip the Vista operating system and either stick with Windows XP or move to Windows 7. Because better tools exist, you may very well want to put a plan together now for converting to another development tool or at least understand what the future is likely to hold. If you're a power-user or researcher working with data, stick with Paradox.

2. Delphi Abstraction (abstract, override)

Delphi for Win32 supports abstract class members using the abstract keyword. You can even instantiate instances of a class that contains abstract members. Then you override each abstract member in a descendant class with Override. Delphi does not support setting an entire class as abstract. You can create an abstract class (a class with one or more abstract methods), but there is no way to tell the compiler to not allow the instantiation of the abstract class. Delphi does not support abstract member properties directly. To implement an abstract properity, make use of abstract methods. That is, you can read a GetPropertyX abstract function and write to a SetPropertyX abstract procedure. In effect, creating  an abstract property.

5. Delphi Prism Member Property (property..read..write)

Like Delphi, Delphi Prism uses a special property keyword to both get and set the values of properties. The read and write keywords are used to get and set the value of the property directly or through an accessor method. For a read-only property, leave out the write portion of the declaration.

You can give properties any visibility you wish (private, protected, etc). It is common in Delphi and Delphi Prism to start member fields with "F" ("FName" in our example) and drop the "F" with properties that manage member fields ("Name" in our example).

Anyone got Delphi Prism?
Anyone currently using or studying Prism? If so, post here. I'd like to know if you're studying it or using it on a real project. Also, did you use Delphi, Delphi for .Net, Oxygene, or Lazarous? We have a few existing Delphi clients we are migrating from Delphi to Delphi Prism this next quarter but I've got Delphi Prism and I'm primarily studying it right now.  I'm filling in the Prisdm data for my Prism Cross Reference Language Guides.
