I know I can do the following from a command prompt:

$ runghc WC < quux.txt

How do I do this in WinGHCi? I know I have to first load the file like this:

Prelude> :load WC

But then what? This doesn't work:

*Main> WC < quux.txt

<interactive>:1:1: Not in scope: data constructor `WC'

<interactive>:1:6: Not in scope: `quux'

<interactive>:1:11: Not in scope: `txt'

Probably something like: *Main> quux <- readFile "quux.txt" *Main> :main quux i.e. you can't do file redirection inside ghci -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
