If I understand you correctly, you want to know how to test some samples of code on your mobile...
If this assumption is correct, install the demo version into the mobile device using activesync...Then all you need to do is to copy the un-zipped the samples files into a folder in your mobile, and load the .sbp file into the B4P IDE...and hit run...
Those .bas files you see are modules and do not work as a stand alone..
Un-like visual studio, with Basic4Ppc, you have the abillity to edit the code directly in the device, without having to use an emulator to preview the result.
