Compiled Turbobasic XL programs run on a 400/800?

Do compiled Turbobasic XL programs run on a 400/800?

[kenjennings]

People have handed me lots of compiled BASIC or Turbo BASIC programs that run fine on the 800.

 

Same rules as applies for anything other program regardless of language or if compiled to machine language or not: if it uses XL or XE specific features it probably is not going to work -- such as memory bank switching, or assuming OS graphics modes 12 to 16 are available, etc, etc, etc.

Best way is, when programming, have a copy of Mapping the Atari and make sure you only use the map associated with 400/800. And if the program has features that rely on the XL or XE OS, they can easily be translated before compilation in many cases ... e.g. the Break Key mapping, which is on location 16 on the old OS and still active on the new OS, but the new OS has a new BREAK key location referenced at 566.
