 I recently downloaded Cbc-2.2.1.zip, compiled using Visual Studio 2005
 without any errors, and started using cbcSolve.exe to solve my MIP problem
 as follows:

 "cbcSolve.exe test.lp -sec 200 -ratio 0.05 -solu out.txt  -solve"

 It goes to completion and the 5% gap limit is reached before the 200 sec
 time limit except that the output file "out.txt" it generates does not
 contain the solution vector. All I get is :

 "Status unknown - objective value               0".

 I tried compiling other versions in your archive with similar results.
 Please let me know if I am doing something wrong. Saving to a binary file
 using option "-saveS outbin.dat" generates a binary output file. I am
 trying to save it to a text file.

 Thanks.

 Sam
