One of these is the ability to write threads in Basic4PPC code rather than only being able to do this in a pre-compiled library. This library provides a Thread object to do this.</span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt">The Thread object of this library is intended for use with the optimising compiler of Basic4PPC version 6 onwards. However it can run, after a fashion, in the IDE and in a legacy compiled application. The library protects itself, and you, if it finds itself running in a legacy mode and issues warnings that functions are not available. The purpose of allowing this is to enable debugging of thread code in the IDE because debugging a compiled application is more tricky than using the debugger in the IDE.</span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt">This library also provides a Process object. It provides the same ability as Shell in Basic4PPC in that it starts a program running alongside a Basic4PPC application. However, unlike Shell, it is possible to  identify if that program is still running and receive an event when it terminates. Process should operate identically whether run in the IDE, legacy compiled or optimised compiled.</span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt">This library requires .NET 2.0 on both desktop and device.</span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt">(c) Andrew Graham - 2008</span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left"><font face="Times New Roman"><span style=" font-size:12pt"><br></span></font></div><div align="left">  </div></body></html> </body></html>
