You can implement what are you looking for with macros and recursion. There are some existing macros on PLaneT---look at control.plt<br><br>In this specific case, a Schemer would probably write:<br><br>(let loop ()<br> (if (something-is-done)
<br> 'end<br> (begin (do-something)<br> (loop))))<br><br>Jay<br><br><div><span class="gmail_quote">On 6/5/06, <b class="gmail_sendername">Mike</b> <<a href="mailto:mikee@mikee.ath.cx">mikee@mikee.ath.cx
