Hi, could you send me the Haskell source for the 'getItem' defn that Hugs chokes on? I'm reasonably certain that it is due to a 0.16 HDirect bug, but want to make sure. A post-0.16 dev snapshot of HDirect's ihc.exe can be found at http://www.dcs.gla.ac.uk/~sof/ihc.zip If it doesn't fix your troubles, please let me know. thanks --sigbjorn Toby Watson <[EMAIL PROTECTED]> writes: > > Hi, > > I'd like to use HaskellScript in ASPs (on the severside). > I've been unable > to find library files for the objects in asp.dll, or make one > myself.
