When emulating IBM-syle 3270 terminals under UNIX (see
_\bt_\bn_\b3_\b2_\b7_\b0(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 example, a 3270 has a
key labeled E\bEE\bEO\bOF\bF 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 E\bEE\bEO\bOF\bF 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 _\bb_\be an initial part of another (although
sequences may _\bs_\bh_\ba_\br_\be initial parts).

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 /_\be_\bt_\bc/_\bt_\be_\br_\bm_\bc_\ba_\bp (see _\bt_\be_\br_\bm_\bc_\ba_\bp(5)); however, note that
often the terminals from various termcap entries will all
use the same _\bm_\ba_\bp_\b3_\b2_\b7_\b0 entry; for example, both 925 and
925vb (for 925 with visual bells) would probably use the
same _\bm_\ba_\bp_\b3_\b2_\b7_\b0 entry. Additionally, there are occasions
when the terminal type defines a window manager, and it
will then be necessary to specify a keyboard name (via the
K\bKE\bEY\bYB\bBD\bD 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 particular function,
followed by a semi-colon (`;'). Each way is a sequence of
strings of _\bp_\br_\bi_\bn_\bt_\ba_\bb_\bl_\be ascii characters enclosed inside sin-
gle quotes (`''); various ways (alternatives) are sepa-
rated by vertical bars (`|').
Inside the single quotes, a few characters are special. A
caret (`^') specifies that the next character is the
31, July 1
MAP3270(5) 1991 MAP3270(5)
``control'' character of whatever the character is. So,
`^a' represents control-a, ie: hexadecimal 1 (note that
`^A' would generate the same code). To generate r\bru\bub\bbo\bou\but\bt
(DEL), one enters `^?'. To represent a control character
inside a file requires using the caret to represent a con-
trol 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 preceeded 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 hav-
ing 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.

The following is the list of 3270 key names that are sup-
ported 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
corresponds closely to the functions that the developers
of the Yale code offer in their product.

cause _\bt_\bn_\b3_\b2_\b7_\b0(_\b1) to send a (possibly visual) bell sequence
to the user's terminal.

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 alphanu-
meric).
