( Find the entry corresponding to word name where (HL) points

to in dictionary having its tip at DE and sets DE to point

to that entry. Z if found, NZ if not. )

HL PUSH,

( First, figure out string len )
|

A (HL) LDrr, A ORr,

( special case. zero len? we never find anything. )

IFNZ, ( fail-B296 )
|

( Let's do something weird: We'll hold HL by the *tail*.
|
|
Because of our dict structure and because we know our
|
|
lengths, it's easier to compare starting from the end. )
|

C A LDrr, B 0 LDri, ( C holds our length )

BC ADDHLd, HL INCd, ( HL points to after-last-char )
