sorry, the test case in the e-mail had a typo and didnt match the test case i was actually using. the 2nd line should clearly be "esac)" variations show that comments between the last ;; and the esac results in an error. other locations work fine. this fails: echo $(case a in (a) echo ok;; # comment esac) this works: echo $(case a in (a) echo ok;; # comment (b) echo moo;; esac) -mike
