I am trying to use the “outlev=1” option and save all the generated information in a log file. But in the end I can’t generate that information. I am going to attach the 3 files corresponding to the model, data set and the instruction file (.run).

I ran the command “ampl TSOP.run” and got the attached log file. Also I tried “include TSOP.run;” at the AMPL command prompt, and got the same result, except that I had to press the “enter” key one more time at the end, to get all of the output to appear.

The log file _does_ need to be left open until the AMPL session completes. Executing “close ‘log\_timetable20230313 19.09.04.log’;” causes a new, empty log file to be started in place of the one that was written.

Are you rnning TSOP.run differently from how I describe? And can you attach the log file that you are seeing?

(Attachment log\_timetable20230313 19.09.04.log is missing)
