map3270 - database for mapping ascii keystrokes into IBM
3270 keys

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 one sequence _\bb_\be an initial part of another (although
sequences may _\bs_\bh_\ba_\br_\be initial parts).
F\bFO\bOR\bRM\bMA\bAT\bT
The file consists of entries for various terminals. The
first part of an entry lists the names of the terminals
which use that entry. These names should be the same as in
/_\be_\bt_\bc/_\bt_\be_\br_\bm_\bc_\ba_\bp (see _\bt_\be_\br_\bm_\bc_\ba_\bp(5)); 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. After the
names, separated by vertical bars (`|'), comes a left brace
(`{'); the definitions; and, finally, a right brace (`}').
The definitions consist 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, fol-
lowed 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 single
quotes (`''); various ways (options) are separated by verti-
cal bars (`|').
Inside the single quotes, a few characters are special. A
caret (`^') specifies that the next character is the ``con-
trol'' 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,\b, one

MAP3270(5) UNIX Programmer's Manual MAP3270(5)
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 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. 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.

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