Thanks for reply . I used braces , since previous error was on indentation and I wasn't sure what was wrong . The intent of the *curr_bank_state = head . filter (\y -> y == (wr_bank,_) state was *get first entry (only entry) from list of tuples (Time,BankStateSIngle) matching condition Time == wr_bank .

After removing braces the message is DdrController.hs:112:8: parse error (possibly incorrect indentation) Failed, modules loaded: none.

Thanks, Lev

Hi Lev

Where clauses don't use braces so that's first problem.

Also this line near the end has a problem:

curr_bank_state = head . filter (\y -> y == (wr_bank,_) state

What should it be doing?

Best wishes

Hi I am getting the following message : parse error on input `= Code in question is attached .

Another general question on haskell : I am not sure I understand correctly the 'where' clause usage , I'll happily accept comments on the code

Thanks, Lev
