Watches and watch sizes

A watch shows the live contents of an address in one of three sizes:

Size	Bytes	Displayed as
Byte	1	$XX (Nd)
Word	2	$XXXX (Nd)
Long	4	$XXXXXXXX (Nd)

Every value is shown in hex and, in parentheses, in decimal: the same value read unsigned (Byte 0 to 255, Word 0 to 65535, Long 0 to 4294967295), for example $D0 (208d).

Word and Long are assembled little-endian, low byte first, matching the Z80's own convention — so a Word watch on a LD (nn),HL destination reads back HL.

A watch on a C variable has no size to choose: it has the variable's own type (Variables).

Watches read through the CPU's current view of memory, so a watch on a banked address follows whatever is paged in at that moment.
