If you're using GHC, take a look at module Readline in the util package (http://www.haskell.org/ghc/docs/latest/set/readline.html). I don't know which other Haskell systems support this module.
The annoying thing is the way that terminals generally act on the ASCII codes so it looks like the delete is working. Readline library sounds like the much the best option; however if it doesn't work it is possible to write a function which postprocesses the returned string and acts on the ASCII codes for backspace, arrow movement, etc, although it's a bit complex as you've got to get easy deletion of points both immediately before and after the point you are considering in the string. ___cheers,_dave_________________________________________________________ www.cs.bris.ac.uk/~tweed/|`...heat generated by its microprocessors will email:tweed@cs.bris.ac.uk|slope upward exponentially, reaching the power work tel:(0117) 954-5250 |density of a nuclear reactor before 2010'-Intel
