[Coin-lpsolver] Interpretation of columnLower() and columnUpper() output in drive r2

[Vansant, Robert]

New user question...

If I run the COIN/Clp/Samples/driver2 example (Nov16 build) on a simple
example:

NAME MYTEST
ROWS
  N 1
  E 2
COLUMNS
    X         2            1.0000000
    X         1            2.0000000
    Y         2            1.0000000
    Y         1            1.0000000
RHS
    RHS       2            1.0000000
ENDATA

I get the, at the end, the output:

Clp0000I Optimal - objective value 1
mytest.mps Objective 1 took 0 iterations and 0 seconds
Model MYTEST has 1 rows and 2 columns
                       Primal          Dual         Lower         Upper
(Cost)
     0        2      1.000000      1.000000      1.000000      1.000000
--------------------------------------
                       Primal          Dual         Lower         Upper
Cost
     0        X      0.000000       1.00000       0.00000  1.79769e+308
2.00000
     1        Y       1.00000       0.00000       0.00000  1.79769e+308
1.00000
--------------------------------------

My interpretation of Lower and Upper bounds (columnLower() and columnUpper()
calls) is that they indicate/return the bounds on the objective coefficients
that would cause the variable to enter or leave the basis, but that doesn't
seem consistent with the column outputs above.  What are these column ranges
indicating?

Many Thanks,
