RHSSEN variables ;
For the dense input format, the RHSSEN statement identifies variables in the problem data set that define change vectors for
examining the sensitivity of the optimal solution to changes in the RHS constants. If the RHSSEN statement is omitted, then
the LP procedure assumes that a variable named _RHSSEN_ contains a right-hand-side change vector.
For the sparse input format, the RHSSEN statement gives the names of one or more columns in the problem data set that are
to be considered as change vectors. If the RHSSEN statement is omitted, then the LP procedure assumes that the column named
_RHSSEN_ or columns with the 'RHSSEN' keyword in the problem data set contain the right-hand-side change vectors. For further information,
see the section Sparse Data Input Format, the section Right-Hand-Side Sensitivity Analysis, and the section Right-Hand-Side Parametric Programming.
