+</PRE><H3><a name="h3-Margins">Margins</a></H3><PRE>
+       SVr4  (and  X/Open Curses) list several string capabilities for setting
+       margins.  Two were intended for use with  terminals,  and  another  six
+       were intended for use with printers.
+
+       <STRONG>o</STRONG>   The two terminal capabilities assume that the terminal may have the
+           capability of setting the left and/or right margin at  the  current
+           cursor column position.
+
+       <STRONG>o</STRONG>   The printer capabilities assume that the printer may have two types
+           of capability:
+
+           <STRONG>o</STRONG>   the ability to set a top and/or bottom margin using the current
+               line position, and
+
+           <STRONG>o</STRONG>   parameterized  capabilities  for setting the top, bottom, left,
+               right margins given the number of rows or columns.
+
+       In practice, the categorization into "terminal" and  "printer"  is  not
+       suitable:
+
+       <STRONG>o</STRONG>   The  AT&amp;T  SVr4  terminal  database  uses <STRONG>smgl</STRONG> four times, for AT&amp;T
+           hardware.
+
+           Three of the four are printers.   They  lack  the  ability  to  set
+           left/right margins by specifying the column.
+
+       <STRONG>o</STRONG>   Other  (non-AT&amp;T) terminals may support margins but using different
+           assumptions from AT&amp;T.
+
+           For instance, the DEC VT420 supports left/right margins,  but  only
+           using a column parameter.  As an added complication, the VT420 uses
+           two settings to fully enable left/right margins (left/right  margin
+           mode,  and  origin  mode).   The  former enables the margins, which
+           causes printed text to wrap  within  margins,  but  the  latter  is
+           needed to prevent cursor-addressing outside those margins.
+
+       <STRONG>o</STRONG>   Both  DEC  VT420  left/right  margins are set with a single control
+           sequence.  If either is omitted, the corresponding margin is set to
+           the  left  or  right  edge  of the display (rather than leaving the
+           margin unmodified).
+
+       These are the margin-related capabilities:
+
+                    <STRONG>Name</STRONG>       <STRONG>Description</STRONG>
+                    ----------------------------------------------

+                    smgtp      Set top margin at line <EM>N</EM>
+
+       When writing an application that uses these  string  capabilities,  the
+       pairs  should be first checked to see if each capability in the pair is
+       set or only one is set:
+
+       <STRONG>o</STRONG>   If both <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG>  are  set,  each  is  used  with  a  single
+           argument,  <EM>N</EM>,  that  gives  the column number of the left and right
+           margin, respectively.
+
+       <STRONG>o</STRONG>   If both <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> are set, each is used to set  the  top  and
+           bottom margin, respectively:
+
+           <STRONG>o</STRONG>   <STRONG>smgtp</STRONG> is used with a single argument, <EM>N</EM>, the line number of the
+               top margin.
+
+           <STRONG>o</STRONG>   <STRONG>smgbp</STRONG> is used with two arguments, <EM>N</EM> and <EM>M</EM>, that give  the  line
+               number of the bottom margin, the first counting from the top of
