function n = p11_n ( )

%*****************************************************************************80
%
%% P11_N returns the number of equations for problem 11.
%
%  Discussion:
%
%    If N is positive, then N is the only value for the number
%    of equations for this problem.
%
%    If N is negative, then the absolute value of N is the
%    MINIMUM possible value for the number of equations for
%    this problem, and all larger values may also be used.
