Also remember that this application is only BASED on BASIC, so most commands are almost completely different. You might want to look in to the code of some of the samples to take a look, and try to learn the commands SmileBASIC uses instead, and the formats for them. For example, 'SPHITSP(cn, start cn, end cn)' is used to check for sprite collision, 'BEEP number' is used to play a noise, so on.
