Print log file with .bat

GAMS
1

Hello Dear GAMS Community,

I need a help.

I´m using .bat files to run lots of .gms instances in GAMS/CPLEX and GAMS/Gurobi.

The problem is, when I do this, the .log of solver is printed in the prompt and I´m not able to get it from there.

I need the log files to analyse the convergence and GAPS of solvers. I only have it when I run the .gms files directly from the GAMS. As aways, the GAMS put the .lst and .log into the project folder.

Does someone know how to get the log of the solver when using the a .bat file to run?

Thanks in advance,
Jack Hagart

hi jack,
have a look at http://support.gams.com/doku.php?id=check_list. they say: “If you are working from the command line, please use the additional command line option lo=2 (e.g. gams trnsport.gms o=2) to redirect the screen output into a log file.”
i think that’s it.

kind regards,
franzi
