neqn(1) neqn(1)

define thing % replacement %

deﬁnes a new token called thing that is replaced by replacement whenever it appears thereafter. The % can

be any character that does not occur in replacement.

Other Keywords

Keywords such as sum (

), int (

∫

), inf (∞), and shorthands such as >= (≥), != (≠), and -> (→) are

recognized. Greek letters are spelled out in uppercase or lowercase as desired, as in alpha (α)orGAMMA

(Γ). Mathematical words such as sin, cos, and log are made Roman automatically. nroff four-

character escapes such as \(dd (‡) and \(bu (•) can be used anywhere.

Verbatim Text

Strings enclosed in double quotes ("string") are passed through untouched; this permits keywords to be

entered as text, and can be used to communicate with nroff when other methods fail. Details are given

in the manuals cited below.

EXTERNAL INFLUENCES

Environment Variables

LC_CTYPE determines the interpretation of text as single- or multibyte characters.

LANG determines the language in which messages are displayed.

If LC_CTYPE is not speciﬁed in the environment or is set to the empty string, the value of

LANG is used as

a default for each unspeciﬁed or empty variable. If

LANG is not speciﬁed or is set to the empty string, a

default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable contains an invalid

setting, neqn behaves as if all internationalization variables are set to "C". See environ(5).

International Code Set Support

Single- and multibyte character code sets are supported.

WARNINGS

To embolden digits, parentheses, etc., it is necessary to quote them, as in

bold "12.3". Also see the

"WARNINGS" section in nroff(1).

Good practice dictates that if a delimiter is speciﬁed in a ﬁle, the

delim off

directive should be included

at the end of the ﬁle to prevent undesirable behavior when processing multiple ﬁles where a subsequent ﬁle

may contain the delimiter character as part of regular text.

To properly display equations on terminal screens and other devices that do not support reverse line feeds,

nroff output should be piped through col (see col(1)).

The display on devices that do not support partial linefeeds is often difﬁcult to understand; Greek charac-

ters and other symbols are often not well supported and can mismatched printing of bold words on the

same line (see a printed version of the "Other Keywords" subsection above). Consider using "computer-

program" coding instead.
