[Help-glpk] is it possible to determine the value a nb variable will take?

Hi, i use lpx_prim_ratio_test() to find out which basic variable
should leave the basis. This variable will either take its lower or
upper bound value to leave the basis.

On the other hand, i have no clue as to what value the entering
nonbasic variable will take on entering the basis. I do not want to
call lpx_warm_up(), it would be costly.
