NAME
       map3270 - database for mapping ascii keystrokes into IBM 3270 keys

SYNOPSIS
       map3270

DESCRIPTION
       When  emulating	IBM-style 3270 terminals under UNIX (see tn3270(1)), a
       mapping must be performed between sequences of keys  hit	 on  a	user's
       (ascii) keyboard, and the keys that are available on a 3270.  For exam‐
       ple, a 3270 has a key labeled EEOF which erases	the  contents  of  the
       current	field from the location of the cursor to the end.  In order to
       accomplish this function, the terminal user and a program  emulating  a
       3270 must agree on what keys will be typed to invoke the EEOF function.

       The requirements for these sequences are:

	   1)	that the first character of the sequence be outside of the
		standard ascii printable characters;

	   2)	that no sequence be an initial part of another (although
		sequences may share initial parts).

FORMAT
       The  file consists of entries for various keyboards.  The first part of
       an entry lists the names of the keyboards which use that entry.	 These
       names  will often be the same as in /etc/termcap (see termcap(5)); how‐
       ever, note that often the terminals from various termcap	 entries  will
       all  use	 the  same map3270 entry; for example, both 925 and 925vb (for
       925 with visual bells) would  probably  use  the	 same  map3270	entry.
       Additionally, there are occasions when the terminal type defines a win‐
       dow manager, and it will then be necessary to specify a	keyboard  name
       (via  the  KEYBD environment variable) as the name of the entry.	 After
       the names, separated by vertical bars (`|'), comes a left brace	(`{');
       the definitions; and, finally, a right brace (`}').

       Each  definition	 consists of a reserved keyword (see list below) which
       identifies the 3270 function (extended as defined below),  followed  by
       an equal sign (`='), followed by the various ways to generate this par‐
       ticular function, followed by  a	 semi-colon  (`;').   Each  way	 is  a
       sequence	 of strings of printable ascii characters enclosed inside sin‐
       gle quotes (`´'); various ways (alternatives) are separated by vertical
       bars (`|').

       Inside  the single quotes, a few characters are special.	 A caret (`^')
       specifies that the next character is the ``control'' character of what‐
       ever  the character is.	So, `^a' represents control-a, ie: hexadecimal
       1 (note that `^A' would generate the same code).	  To  generate	rubout
       (DEL), one enters `^?'.	To represent a control character inside a file
       requires using the caret to represent a control sequence; simply typing
       control-A  will not work.  Note: the ctrl-caret sequence (to generate a
       hexadecimal 1E) is represented as `^^' (not `^\^').

       In addition to the caret, a letter  may	be  preceded  by  a  backslash
       (`\').	Since  this  has little effect for most characters, its use is
       usually not recommended.	 For the case of a  single  quote  (`´'),  the
       backslash  prevents that single quote from terminating the string.  For
       the case of a caret (`^'), the backslash prevents the caret from having
       its  special  meaning.  To have the backslash be part of the string, it
       is necessary to place two backslashes ('\\') in the file.

       In addition, the following characters are special:

	    `\E'  means an escape character;
	    `\n'  means newline;
	    `\t'  means tab;
	    `\r'  means carriage return.

       It is not necessary for each character  in  a  string  to  be  enclosed
       within single quotes.  `\E\E\E' means three escape characters.

       Comments,  which	 may appear anywhere on a line, begin with a hash mark
       (`#'), and terminate at the end of that line.  However, comments cannot
       begin inside a quoted string; a hash mark inside a quoted string has no
       special meaning.

3270 KEYS SUPPORTED
       The following is the list of 3270 key names that are supported in  this
       file.   Note  that  some	 of the keys don't really exist on a 3270.  In
       particular, the developers of this file have relied extensively on  the
       work  at	 the  Yale University Computer Center with their 3270 emulator
       which runs in an IBM Series/1 front end.	  The  following  list	corre‐
       sponds  closely	to  the functions that the developers of the Yale code
       offer in their product.

       In the following list, the starred ("*") functions are not supported by
       tn3270(1).   An	unsupported  function  will  cause tn3270(1) to send a
       (possibly visual) bell sequence to the user's terminal.

BUGS
       Tn3270  doesn't	yet understand how to process all the functions avail‐
       able in map3270; when such a function is requested tn3270 will beep  at
       you.

       The  definition	of  "word"  (for "word erase", "word tab") should be a
       run-time option.	 Currently it is defined  as  the  kernel  tty	driver
       defines	it  (strings  of  non-whitespace);  more than one person would
       rather use  the	"vi"  definition  (strings  of	specials,  strings  of
       alphanumeric).
