TEXT: H          _a_r_g, ... to be _e_x_p_r_e_s_s_i_o_n, which may involve the argu-
TEXT: H          ments. When the function is later used, the arguments

TEXT: H          when it is parsed.  If _e_x_p_r_e_s_s_i_o_n is not present, any

TEXT: H          This command is intended to make Gnutmeg Heasier to use
TEXT: H          with simulators other than SPICE3.  It is only a tem-
TEXT: H          porary facility, however.  The first form defines a new
TEXT: H          type for vectors.  The _t_y_p_e_n_a_m_e may then be used as a
TEXT: H          vector type specification in a rawfile, and will be
TEXT: H          used for the Gdisplay Hcommand to indicate the type.  If
TEXT: H          an _a_b_b_r_e_v is given, values of that type can be named
TEXT: H          _a_b_b_r_e_v(_s_o_m_e_t_h_i_n_g) where _s_o_m_e_t_h_i_n_g is the name given in
TEXT: H          the rawfile (and _s_o_m_e_t_h_i_n_g doesn't contain
TEXT: H          parentheses).  The second form defines a plot type.
TEXT: H          The (one word) name for a plot with any of the _p_a_t_t_e_r_ns
TEXT: H          present in its plot type name as given in the raw file
TEXT: H          will be _p_l_o_t_t_y_p_e<_n_u_m>, where <_n_u_m> is a positive
