Hi Ved,

yes, it is not a perfect equivalent of break. You would need an  
'else' clause:

a=0;
for (i=0; i<100; i++) {
   a++;
   if (a==3) i=1e99; //break if this condition is fulfilled
   else { //put everything after 'break' here
     print ("code2 after break: a="+a);
   }
}

Of course, the solution of Michael Ellis with 'i<100 & !done' in the  
'for' statement may be considered more elegant.
