function y = mpsy_maxreversal_askagain(n_maxreversal) 

% to be called from mpsy_init_run
% ----------------------------------------------------------------------
% Usage: y = mpsy_maxreversal_check(n_maxreversal)
%
%  this function checks whether the max. number of reversals is OK,
%  or whether it is unintentionally low due an older experiment,
%  written prior to psylab version 2.6.
%
%   input:   ---------
%        n_maxreversal   the current maximum number of reserversals
%  output:   ---------
%       y    set to 1 if the number of resersals shall be checked
%            again for any next experiment 
%            set to 0 if the number of reversals shall no longer be
%            checked for any experiment
