a) you can't. At least, not without carnal knowledge of your system. It's an infinate loop, by design, so if you find you need to jump out of it, it means you shouldn't be using it ;-)

Example code using AGAIN: http://turboforth.net/lang_ref/view_word.asp?ID=71

b) See this example for do/loop with LEAVE: http://turboforth.net/lang_ref/view_word.asp?ID=83

c) n case
  a of code-for-case-a endof
  b of code-for-case-b endof
  c of code-for-case-c endof
  code-for-no-matching-case
endcase

Example code using CASE: http://turboforth.net/lang_ref/view_word.asp?ID=74

Obviously, if case a b or c *is* detected, then the default (i.e. no match) code is *not* executed.

Have a look at BEGIN...UNTIL. That might be better for your needs. Here's an example:
