View Ref-File7.7.20  Bindings für vrq_string                                    TOS

 C:         void vrq_string ( int16_t handle, int16_t max_length, 
            int16_t echo_mode, int16_t *echo_xy, int8_t *string );

 Umsetzung:

            void vrq_string (int16_t handle, int16_t max_length,
                             int16_t echo_mode, int16_t *echo_xy,
                             int8_t *string)
            {
               int16_t tmp;
 
               intin[0] = max_length;
               intin[1] = echo_mode;
               ptsin[0..1] = echo_xy[0..1];
 
               contrl[0] = 31;
               contrl[1] = 1;
               contrl[3] = 2;
               contrl[6] = handle;
 
               vdi ();
 
               for (tmp = 0; tmp < contrl[4]; tmp++)
                  *string++ = intout[tmp];
 
               *string = 0;
            }
