vtenb (2) --- enable input on a particular screen line 07/11/84 | _C_a_l_l_i_n_g _I_n_f_o_r_m_a_t_i_o_n subroutine vtenb (row, column, length) integer row, column, length | Library: vswtlb (standard Subsystem library) _F_u_n_c_t_i_o_n 'Vtenb' enables input in a field with a particular length, starting at the given (row, column) on the screen. Any areas of the screen that are not enabled by 'vtenb' cannot be used for entry of data; therefore 'vtenb' must be called before 'vtread' can be used. _I_m_p_l_e_m_e_n_t_a_t_i_o_n 'Row' is checked as being on the screen, and if not, an immediate return is executed and input is not enabled at that location. 'Column' and 'length' are checked as being on the screen, and if the values specified "run off" the screen, the length is truncated to the border of the screen. Input is then enabled starting at (row, column) for 'length' characters, or to the border of the screen. _B_u_g_s Allows only one input area per line. _S_e_e _A_l_s_o other vt?* routines (2) vtenb (2) - 1 - vtenb (2)
