Library /sys$common/syshlp/basichelp.hlb Graphics, SET Statements, INPUT_PRIORITY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The  SET  INPUT  PRIORITY  statement  allows  you  to  specify   which
  transformation  should  have  the  highest  priority when interpreting
  input points from a device.  Unless you include  this  statement,  the
  current  transformation  is  automatically the transformation with the
  highest input priority.

  Example

  SET WINDOW ,TRAN 2 : 0,100,0,100
  SET TRANSFORMATION 1
  MAT GRAPH POINTS xs, ys
  !Set highest priority to TRAN 2 for input
  SET INPUT PRIORITY 2 > 1
  MAT GET POINTS : x_coords, y_coords
