The compiler works great as is right now, I mean, if you use the extra RAM as a data storage facility, as I usually do. The same happens to z88dk, it's not very "128K ready" (not even aware), but it's perfectly usable. You just have to remember, in the case of ZX Basic, that ROM 1 must be paged in Meet this requirement, and you can make 128K programs

Please, check the latest version (uploaded just yesterday). It shouldn't crash when you try to convert a string into a byte (but complain with an error instead).
Also, I will check your example today to see if I catch why ROM paging is crashing the compiler.
