On xIN, the stack goes to eight levels (but can be changed back to four if required), the device also enters double precision mode (which can't be changed back). These are the big two and xIN/xOUT is sufficiently useful to make putting up with them worthwhile.

The other changes are pretty minor. The A..D-> instruction becomes useful to create a small number of temporary registers but LocR is better practice. Branches lose their labels -- they are either replaced with relative branches or operate via a pre-computed jump table. CNVG? sometimes changes how it operates slightly to provide better single precision results.


The biggest change that causes most problems moving code to XROM is the eight level stack.
