These samples help you to understand how powerful the watch expressions are:
[XPOS:W]
Displays the two bytes stored in the memory at the address pointed by the XPOS symbol.
[`Z ? XPOS : YPOS :W]
If the Z flag is set, reads the two bytes stored at the XPOS address; otherwise retrieves
the two bytes from YPOS address.
DE*HL
Displays the value of DE and HL registers multiplied. The result is a double word (32 bits).
[#4000:DW] & [MASK:DW] :%32
Reads the four bytes stored at the #4000 address. Uses the four bytes store at the
address pointed by MASK and executes a bitwise AND operation on these two 32-bit values.
Displays the result as a 32-bit binary vector.
