[Cbc] [Clp] GNUMath Prog

[Michal Kaut]

Dear Horaldo

For the first, it should be
cbc posmDTF.mat%comp-2007-2-17.dat solve solu solu.txt

For the second, this only prints the values for the columns.
In GMPL, however, one can do formatted output using display and printf 
commands, which gives much better reporting options.
Once again, as far as I remember, Symphony processes these output 
commands, while Cbc simply ignores them.
