This is the error that I have: ERROR "c:\textanalysis.HS":48 - Syntax error in declaration (unexpected `->')
Line 48:
________________________putWordStat(Word,WordCount)->IO()
There is a :: missing between the function name and its type.
________________________putWordStat::(Word,WordCount)->IO()
The function definition is also missing an = sign:
________________________putWordStat(w,wc) ________________________do
should be
________________________putWordStat(w,wc)= ________________________do
Finally, in this whole block:
________printFreq wl=do sequence (map putWordStat wl) ________________________where ________________________putWordStat::(Word,WordCount)->IO() ________________________putWordStat(w,wc)= ________________________do ... ________________________return() ________________________wlLength-countWords wl;
the indentation is incorrect. You probably meant to write something along these lines:
________printFreq wl=do sequence (map putWordStat wl) ____________________________where ______________________________putWordStat::(Word,WordCount)->IO() ______________________________putWordStat(w,wc)= ________________________________do ... ___________________________________return() ________________________wlLength-countWords wl;
but even this has two faults. First, a `where' clause can only be attached to a whole definition, not to a single statement within a `do'. Second, the final statement of the outer `do' should be a statement e.g. "return (wlLength-countWords wl)", not a simple value. Regards, Malcolm
