Train Control Language

TCL (or Train Control Language) is used to tell Tcc what to do. It is a scripting language rather different to 'normal' programming languages and is very suited to the sort of control that is required for a model railway. If you have experience with other languages then this may appear rather different. If you have no programming experience you are probably at an advantage!
