I am a (very) new Haskell user, having spent many years working in Prolog. I have just installed HUGS on my laptop in Windows XP, and it is working well except for one strange problem. I cannot load more than one file at a time. If I use ':load fn1 ...fnk' I receive an error message that the module has already been loaded. Only the first file is then loaded. If I attempt to load the files separately in sequence using either :l or :also, each successive loading of a file overides and cancels the previous one. What am I doing wrong? I would appreciate your help on this. Thanks. Regards.
Do your modules start with `module Foo where'? If not, they'll all default to Main, and Hugs doesn't let you load two modules with the same name. But even then it may not be what you want (all names from all the modules in scope). Hugs only has one current module at a time, whose contents are in scope; if you load several modules, this will be the last one. You'll probably need to use Haskell imports and exports to get what you want.
