        The  <STRONG>form</STRONG> library provides terminal-independent facilities
        for composing form screens  on  character-cell  terminals.
        The  library  includes:  field  routines, which create and
        into forms, display forms on the screen, and handle inter-
        action with the user.
 
-       The <STRONG>form</STRONG> library uses the <STRONG>curses</STRONG> libraries, and  a  curses
-       initialization  routine  such  as  <STRONG>initscr</STRONG>  must be called
-       before using any of these  functions.   To  use  the  <STRONG>form</STRONG>
-       library, link with the options <STRONG>-lform</STRONG> <STRONG>-lcurses</STRONG>.
+       The <STRONG>form</STRONG> library uses the <STRONG>curses</STRONG> libraries.   To  use  the
+       <STRONG>form</STRONG> library, link with the options <STRONG>-lform</STRONG> <STRONG>-lcurses</STRONG>.
 
+       Your program should set up the locale, e.g.,
 
-   <STRONG>Current</STRONG> <STRONG>Default</STRONG> <STRONG>Values</STRONG> <STRONG>for</STRONG> <STRONG>Field</STRONG> <STRONG>Attributes</STRONG>
-       The  <STRONG>form</STRONG>  library  maintains  a  default  value for field
-       attributes.  You can get or set this  default  by  calling
-       the  appropriate  <STRONG>set_</STRONG>  or  retrieval  routine with a <STRONG>NULL</STRONG>
-       field pointer.  Changing this default with a <STRONG>set_</STRONG> function
-       affects  future  field  creations, but does not change the
-       rendering of fields already created.

-   <STRONG>Routine</STRONG> <STRONG>Name</STRONG> <STRONG>Index</STRONG>
-       The following table lists each <STRONG>form</STRONG> routine and  the  name
-       of the manual page on which it is described.
+       so that input/output processing will work.
 
+       A  curses  initialization  routine such as <STRONG>initscr</STRONG> must be
+       called before using any of these functions.
