Error reading .lst file

[Thanh Tung]

Dear GAMS experts,

After running a large set of data, I have got the error “Error = Error 0: The operation completed successfully” and can’t open .lst file. Then, from the new window of Gamside, I have tried to open that .lst file again and got error: “Access violation at address 006E5D38 in module ‘gamside.exe’. Read of address 00000356”.

My .lst file is more than 2.9Gb.

Please give me your advices. Thank you very much.

Diep Thanh Tung.

Dear Tung

That may happen when you have a large input file. If that is the same for you, use $offlisting and $onlisting to stop writing the LARGE input parameters to the listing file. These keywords should appear just before and after the targeted part, respectively.

If that does not work, adding other commands such as $offecho or MODEL_NAME.limcol = 0;   MODEL_NAME.limrow =0 might be helpful.

I hope that helps.

Hi,

Are you using a Display statement inside a loop?
That can result in a lot of output.

At the end of your run, you can write your data to a gdx file
and view the gdx file inside the gamside.

Hi Paul, Hi Tavallali,

Thank you so much for your replies. You’re right, I have other large inputs including more than 10.000 observations and the .lst file is nearly 10Gb. GAMS runs well until the end and it cannot show .lst file because of the large file (I think so).Alternatively I tried to use LTF software for showing large .txt file from gamsdir folder saved, and it’s good.

However, I think your suggestions for using $offlisting and $onlisting, or write a gdx file may be better solutions. I am going to try both.

Again, thank you for your useful helps,

Tung.
