_v_a_r_N_a_m_e. The value of the variable must be an integer. If
_i_n_c_r_e_m_e_n_t is supplied then its value (which must be an
integer) is added to the value of variable _v_a_r_N_a_m_e; other-
wise 1 is added to _v_a_r_N_a_m_e. The new value is stored as a
decimal string in variable _v_a_r_N_a_m_e and also returned as
result.
