Multiple conditions in a While Loop - IDL

Question

I am trying to create a multiple condition while loop in IDL with no success. For example:

while (delta_flux gt 1.0) or (lt -1.0) do begin
;something here...
endwhile

returns:

IDL> .run flare_finder_while_attempt5.pro

      while (delta_flux gt 1.0) or (lt -1.0) do begin
                                    ^
% Syntax error.

Is there a way of doing this?

Try:

while (delta_flux gt 1.0) or (delta_flux lt -1.0) do begin
