The SPECIAL-NAMES paragraph: (1) associates compiler features and
OpenVMS logical names with user-defined mnemonic-names, (2) defines
symbolic-characters, (3) specifies the currency sign, (4) selects the
decimal point, (5) relates alphabet-names to character sets or
collating sequences, (6) relates class-names to character sets,
(7) provides for cursor positioning for an ACCEPT (Format 5) statement,
and (8) provides information on the cause of termination of an ACCEPT
(Format 5) statement.

1 – device-name
is a mnemonic-name for a device. It always possesses the global attribute. Only the ACCEPT and DISPLAY statements can refer to it.
2 – top-of-page-name
is the first line of a logical page (top-of-page). It always possesses the global attribute. Only the WRITE statement can refer to it.
3 – switch-num
is the number of a program switch. Its value can range from 1 through 16.
4 – switch-name
is a mnemonic-name for the program switch.
5 – cond-name
is a condition-name for the "on" or "off" status of the switch. It always possesses the global attribute. Its truth value is "true" when the STATUS phrase matches the status of the switch, "false" when it does not.
6 – alphabet-name
is the user-defined word for a character set and/or collating sequence. It always possesses the global attribute.
7 – first-literal
is a literal. It specifies: (1) the value of one or more alphabetic characters, or (2) the first in a range of values.
8 – last-literal
is a literal. It specifies the last in a range of values.
9 – lit
is a literal. It specifies an alphabetic character value.
10 – symbolic-char
is a user-defined word that names the symbolic-character. It always possesses the global attribute. The same symbolic-char cannot appear more than once in the SYMBOLIC CHARACTERS clause.
11 – char-val
is an integer that indicates the ordinal position of a character in the native character set.
12 – class-name
is the user-defined word for a class. It always possesses the global attribute
13 – char
is a one-character nonnumeric literal that specifies the currency symbol. It cannot be a symbolic character.
14 – cursor-position
is a data item declared in the Working-Storage Section of the program. It is either an elementary unsigned numeric integer either four or six characters in length, described as USAGE IS DISPLAY, or a group item either four or six charaters in length, consisting of two elementary unsigned data items.
15 – crt-status-code
is a group data item three characters in length, declared in the Working-Storage Section of the program.
