Abstract
Qualitative properties shared by the solutions to the family of linear equations of the form $$Ax=b, quad (Ain C, b in B),eqno(1)$$ where C is a cone in ${shadR}{mtimes n}$ and B is a cone in ${shadR}m$ are studied. In particular, the cones C and B for which the sign patterns of the solutions to (1) are independent of the choice of A 
C and b B are characterized.
