| The function <STRONG>set_current_field</STRONG> sets the current field of the given |
| form; <STRONG>current_field</STRONG> returns the current field of the given form. |
| |
| The function <STRONG>unfocus_current_field</STRONG> removes the focus from the current |
| field of the form. In such state, inquiries via <STRONG>current_field</STRONG> shall |
| return a NULL pointer. |
| |
| The function <STRONG>set_form_page</STRONG> sets the form's page number (goes to page <EM>n</EM> |
| of the form). |
| |
| The function <STRONG>form_page</STRONG> returns the form's current page number. |
| |
| The function <STRONG>field_index</STRONG> returns the index of the field in the field |
| array of the form it is connected to. It returns <STRONG>ERR</STRONG> if the argument |
| is the null pointer or the field is not connected. |
| |
| |
| </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> |
