+ 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&T SVr4 terminal database uses <STRONG>smgl</STRONG> four times, for AT&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&T) terminals may support margins but using different
+ assumptions from AT&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>
+ ----------------------------------------------
+ smgl Set left margin at current column
+ smgr Set right margin at current column
+ smgb Set bottom margin at current line
+ smgt Set top margin at current line
+ smgbp Set bottom margin at line <EM>N</EM>
+ smglp Set left margin at column <EM>N</EM>
+ smgrp Set right margin at column <EM>N</EM>
+ 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
+ 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.
+
+ When setting margins, the line- and column-values are zero-based.
+
+ The <STRONG>mgc</STRONG> string capability should be defined. Applications such as
+ <STRONG><A HREF="tabs.1.html">tabs(1)</A></STRONG> rely upon this to reset all margins.

+.IP
+Three of the four are printers.
+They lack the ability to set left/right margins by specifying the column.
+.bP
+Other (non-AT&T) terminals may support margins
+but using different assumptions from AT&T.
+.IP
+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.
+.bP
+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).
+.PP
+These are the margin-related capabilities:
+.TS
+center;
+l l
+_ _
+lw8 lw18.
+\fBName Description\fP
+smgl Set left margin at current column
+smgr Set right margin at current column
+smgb Set bottom margin at current line
+smgt Set top margin at current line
+smgbp Set bottom margin at line \fIN\fP
+smglp Set left margin at column \fIN\fP
+smgrp Set right margin at column \fIN\fP
+smgtp Set top margin at line \fIN\fP
+.TE
+.PP
+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:
+.bP
+If both \fBsmglp\fP and \fBsmgrp\fP are set,
+each is used with a single argument, \fIN\fP,
+that gives the column number of the left and right margin, respectively.
+.bP
+If both \fBsmgtp\fP and \fBsmgbp\fP are set,
+each is used to set the top and bottom margin,
+respectively:
+.RS 4
+.bP
+\fBsmgtp\fP is used with a single argument, \fIN\fP,
+the line number of the top margin.
+.bP
+\fBsmgbp\fP is used with two arguments, \fIN\fP and \fIM\fP,
+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.
+.RE
+.IP
+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 \fBsmgbp\fP to set the bottom margin,
+both arguments must be given.
+.PP
+Conversely, when only one capability in the pair is set:
+.bP
+If only one of \fBsmglp\fP and \fBsmgrp\fP is set,
+then it is used with two arguments,
+the column number of the left and right margins, in that order.
+.bP
+Likewise, if only one of \fBsmgtp\fP and \fBsmgbp\fP 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.
+.IP
+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
+\fBsmglp\fP and \fBsmgrp\fP or
+\fBsmgtp\fP and \fBsmgbp\fP should be defined,
+leaving the other unset.
+.PP
+When setting margins, the line- and column-values are zero-based.
+.PP
+The \fBmgc\fP string capability should be defined.
+Applications such as \fBtabs\fP(1) rely upon this to reset all margins.

Besides providing more reliable operation than AT&T's utility,
-a portability problem is introduced by this analysis.
+a portability problem is introduced by this analysis:
An OpenBSD developer adapted the internal library function from ncurses
-to allow \fBtput\fP to interpret multiple commands on a line.
+to port NetBSD's termcap-based \fBtput\fP to terminfo.
+That had been modified to interpret multiple commands on a line.
Portable applications should not rely upon this feature;
ncurses provides it to support applications written
specifically for OpenBSD.
