Hi, the behaviour you're seeing is intentional. To enable the extensions, you need to use the -98 option when starting up Hugs. There's a couple of ways of doing that (depending on what platform you're on): * add -98 to the command-line used when invoking Hugs * on non-Windows platforms, add -98 to your HUGSFLAGS environment variable. * on Windows platforms, start up the interpreter in Hugs mode via the start menu. If you want to change the default and always start up in 'Hugs mode', you can do this, somewhat indirectly, by changing one of the other options, so that the option set is persisted to the Registry. e.g., try doing ":set -t" hth --sigbjorn ----- Original Message ----- From: Christy To: hugs-bugs@haskell.org Sent: Thursday, January 17, 2002 06:46 Subject: Hugs 98 To Hugs, Hi, I do not think this is a bug but this is the closest email address to someone who I could email that could possibly help me out. Ok, my question is when you first start up Hugs 98, you see this line printed under the version #, Haskell 98 mode: Restart with command line option -98 to enable extensions. Now I was trying to set option -98 to enable extensions but it keeps giving me error saying Haskell 98 compatibility cannot be changed while the interpreter is running. So now I was wondering, how do I set this option (ie enable extensions). If anyone could shed some light onto this, this would be greatly appreciated. Thank you for your time and hope to get an email from you asap. Christy ------------------------------------------------------------------------------ Do You Yahoo!? Send FREE video emails in Yahoo!
