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"

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
