Missing Values
The LP procedure treats missing values as missing in all
rows except those that identify either upper or lower bounds
on structural variables. If the row is an upper-bound row,
then the type identifier is UPPERBD and the LP procedure
treats missing
values as +INFINITY. If the row is a lower-bound row, then
the type identifier is LOWERBD and the LP procedure treats the missing
values as 0, except for the variables that are identified as UNRSTRCT.
