FUNCTION:
Position Relative
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 x,y,z,w PRX=x PR a,b,c,d,e,f,g,h where
x,y,z,w are signed integers in the range -2147483648 to 2147483647 decimal.
"?" returns the current incremental distance for the specified axis.
