Purpose
When a model is loaded, the rows, columns and sets of the model may not have
names associated with them. This may not be
important as the rows, columns and sets can be referred to by
their sequence numbers. However, if you wish row, column and set names to appear in the ASCII solutions
files, the names for a range of rows or columns can be added with
XPRSaddnames.
