The sleep.exe executable distributed with the GAMS system for Windows by default continues running until the specified number of seconds has elapsed. At a command line enter sleep –help for more information. For some applications, a finer resolution could be useful:

• Under Windows, the Windows Server 2003 Resource Kit Tools (google to locate this) contains a sleep executable that works with a millisecond resolution.
• Under UNIX the command usleep sleeps some number of microseconds. Check sleep –help for more information.
