If you prefer to use a command line ftp-client, please follow these steps (we use the setup file for Windows 32 bit (distribution 23.0) as example):
$ ftp ftp.gamsworld.org
User: anonymous
Password: [your_email_address]
ftp> bin
ftp> cd 23.0/windows
ftp> get windows_x86_32.exe
ftp> exit
Please refer to the Windows Installation Notes or the UNIX Installation Notes for more information about the necessary steps to setup a GAMS system. The complete system documentation and release notes can be found online.

- Number of discrete variables: 50 (including semi continuous,
semi integer and member of SOS-Sets)
