%  QUERYFRAME used by PLOTCLAW1, PLOTCLAW2 and PLOTCLAW3 to loop through data.
%
%      QUERYFRAME is normally called directly from PLOWCLAW, and so is
%      not typically called by the user.  However, the user can supress the
%      query option by setting the 'NoQuery' parameter to 1.  This is used
%      for example, in making movies.
%
%      See also PLOTCLAW1, PLOTCLAW2, PLOTCLAW3.

if exist('NoQuery')
  if NoQuery == 1
    % set NoQuery=1 if you want the plots to be produced with no
    % query in between.  Particularly useful if you want lots of frames to
    % be printed out for an animation (put a command like makeframegif
    % in afterframe.m and set NoQuery=1)
    pause(1)
    Frame = Frame + 1;
    if Frame > MaxFrames
      break;   % break out of plotclawN after last frame
    end
    return
