+Instructions deal with unsigned 8-bit values (\fIbytes\fP) and unsigned 16-bit values (\fIshorts\fP). There are no other built-in data types. Occasionally values are treated as signed, such as when loading, storing, or jumping with a relative address.

+Short values are stored on the stack in big-endian byte order: the least significant byte will be on the top of the stack. This makes \fB#abcd\fB is equivalent to \fB#ab #cd\fB.
