How to build a Application...

Warning: Some of this stuff requires programming experience in OPL32 on either a Psion Series 5 or a Geofox One
This is not a beginners course! You must already be able to build a better program than 'hello world'...

If you are looking for an introduction to programming, you should point your browser to 3Lib where Steve Litchfield have an excellent beginners course...
(I write this stuff when it suits me. The reason it's a little bit disorganised is that it's written when I learn something new :-)
