+       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

+
+       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
+               the  page  and  the  second  counting  from  the  bottom.  This
+               accommodates the two styles of specifying the bottom margin  in
+               different manufacturers' printers.
+
+           When  designing  a terminfo entry for a printer that has a settable
+           bottom margin, only the first or second argument  should  be  used,
+           depending on the printer.  When developing an application that uses
+           <STRONG>smgbp</STRONG> to set the bottom margin, both arguments must be given.
+
+       Conversely, when only one capability in the pair is set:
+
+       <STRONG>o</STRONG>   If only one of <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> is set, then it  is  used  with  two
+           arguments, the column number of the left and right margins, in that
+           order.
+
+       <STRONG>o</STRONG>   Likewise, if only one of <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> is set, then  it  is  used
+           with  two  arguments  that give the top and bottom margins, in that
+           order, counting from the top of the page.
+
+           When designing a terminfo entry for a printer that requires setting
+           both  left and right or top and bottom margins simultaneously, only
+           one capability in the pairs <STRONG>smglp</STRONG> and  <STRONG>smgrp</STRONG>  or  <STRONG>smgtp</STRONG>  and  <STRONG>smgbp</STRONG>
+           should be defined, leaving the other unset.
+
+       Except  for  very  old terminal descriptions, e.g., those developed for
+       SVr4, the scheme just described  should  be  considered  obsolete.   An
+       improved set of capabilities was added late in the SVr4 releases (<STRONG>smglr</STRONG>
+       and <STRONG>smgtb</STRONG>),  which  explicitly  use  two  parameters  for  setting  the
+       left/right or top/bottom margins.
+
