Description
Updated 2013-Jan-10: Added Delphi XE3 version of the demo

This is the source code for the EDN article "Delphi Labs: DataSnap XE - Simple Calculator Service".
We are using Delphi XE to build simple calculator service for performing basic arithmetic operations like add, subtract, multiply and divide.
This step-by-step tutorial is intentionally very simple, so even not experienced Delphi programmers should be able to build projects described here. The objective of this lab exercise is to get familiar with basic steps needed for building DataSnap servers and clients.
Our “Simple Calculator Service” will consist of a server and a client. Both programs will be Delphi VCL Forms Win32 applications and will use TCP/IP as the communication protocol.

Note that DataSnap XE is the feature of Delphi XE Enterprise or Delphi XE Architect.
