[slime-devel] How to 'start again'

After running a program a few times (C-c C-k) the output is not longer showing the program output. Possibly due to errors in the program that I'm developing (compile errors show etc). Is there a way to 'clear' out the buffers and start again? I.e. to clean the lisp environment and restart? TIA -- Dave Pawson XSLT XSL-FO FAQ. http://www.dpawson.co.uk
