Re: A86: String comparison
compares (hl) to (de)
strings are preceded by a length BYTE
strings are compared even if length is different
on return:
a will be the last byte compared from (hl)
b will be the number of bytes left in the shorter string
flags will reflect a cp of the last byte
if the string compare the same up to the last byte in the smaller string,
their lengths are compared, a will be the length of (hl), b will be 0
all other registers are preserved!
