DESCRIPTION:

The PR command sets the incremental distance and direction of the next move. The move is

referenced with respect to the current position. If a ? is used, then the current incremental

distance is returned (even if it was set by a PA command). Units are in quadrature

counts.

ARGUMENTS: PR n where

n is a signed integer in the range -2147483648 to 2147483647 decimal

“?” returns the current incremental distance

USAGE:
