Edge intrinsic rotation was investigated in Ohmic L-mode discharges on the Tokamak a Configuration Variable, scanning the major radial position of the X point, R-X. Edge rotation decreased linearly with increasing RX, vanishing or becoming countercurrent for an outboard X point, in agreement with theoretical expectations. The core rotation profile shifted fairly rigidly with the edge rotation, changing the central rotation speed by more than a factor of two. Core rotation reversals had little effect on the edge rotation velocity. Edge rotation was modestly more countercurrent in unfavorable than favorable del B shots.
