In his book "HP-41 / HP-48 Translations", Bill Wickes mentions that the
command << ... CONT ... >> breaks you out of a subroutine and back into the
next level.  I would think that you could include a local subroutine that
would do your loop for you.

For example, the program

<<
.
.
<< a b FOR c
  .
  .
  .
  IF ... THEN CONT END
  .
  .
>>
.
-> loop
.
.
loop EVAL
.
.
>>

may do it for you.
