Using GAMS on MAC

GAMS
1

I have installed GAMS on my MacBook Air.

While trying to run my code I got a series of errors all pointing to the GAMS environment.
I have used Excel for input/output of my data and thus use GDX files which I learnt are meant for Windows OS.
What is the work around for the GDX file if I want to use GAMS on my MacBook ? Is there any other way ?

thanks in advance for your help.

Hi
Please read the guidelines: Your question is too general: be more specific and attach code that generates the errors.

Thanks Renger for your response.

My problem is as follows:

I have a GAMS code for Economic Despatch of Generation (Power Generation) which is perfectly working on a Windows environment. The input data is placed in an Excel file and I have used GDXXRW function for input and output which creates the “.gdx” files. When I used the same perfectly working code on my MacBook Air, it does not create the GDX files and is unable to read/write the data and hence, getting a series of errors.

Based on above, I have a feeling that this could be an issue related to the Mac OS environment settings. Further, someone also told me that GDX files are not available for the Mac OS environment. I do not know which is true and what is solution in terms of changing either the environment or the code. But I do believe, that even on Mac OS environment there must be a way to read & write from/to MS Excel. I need to learn how to do this.

I am also attaching the code and the data file for your ready reference.

Thanks once again in advance for your help.

Hi

You can find an answer to your question right here in the forum. As an alternative you could install Wine/Bottler on your Mac and run Gams as a windows program.
