Used by the routine at NAME_MATCHES.
A word that was not typed -- zero -- fits anything. Otherwise only the twelve-bit dictionary offset is compared, not the flag nibble above it. Both pointers move on two bytes either way.

| 7234 | LD A,(IY+$01) | Same top half of the twelve-bit offset, ignoring the flag nibble... | ||

| 723A | JR NZ,WORD_MATCHES_0 | |||
