Just out of interest, how would you code the following, especially with regard to an if without an else being a bug/bad design.

while .t.
  < some code >

  if < condition >
    exit
  endif

  < some other code >
enddo

the best I get is

< ensure condition true >
while < condition >
  < some code >

  if not < condition >
    < some other code >
  endif
enddo
