Row 57. The pushed ledger (row 37, no window) recorded the tile a macro
set out from when the cartridge moved the fly. For a TALK that is the
tile the script fired on; for a walk it can be the far side of the map.
Pewter City's youngster takes the joypad on four tiles by the road east,
GO ROUTE aims east at Route 3 every time, and one walk from the town's
south entrance walled the south entrance, twenty-six tiles from the
script. Walks start wherever the last one ended, so the walls fenced the
fly into a pocket no route could leave.
A walk now records the tile it last stood the fly on, which is where the
cartridge took over. Every other macro keeps the tile it started on.
