NAME

asa - interpret ASA carriage control characters

SYNOPSIS

asa [ﬁles]

DESCRIPTION

asa interprets the output of FORTRAN programs that utilize ASA carriage control characters. It

processes either the ﬁles whose names are given as arguments, or the standard input if

- is speciﬁed or if

no ﬁle names are given. The ﬁrst character of each line is assumed to be a control character. The following

control characters are interpreted as indicated:

(blank) Output a single new-line character before printing.

(space) (XPG4 only.) The rest of the line will be output without change.

0 Output two new-line characters before printing.

0 (XPG4 only.) A <newline> shall be output, then the rest of the input line.

1 Output a new-page character before printing.

+ Overprint previous line.

+ (XPG4 only.) The <newline> of the previous line shall be replaced with one or more

implementaions-deﬁned characters that causes printing to return to column position 1, fol-

lowed by the rest of the input line. If the + is the ﬁrst character in the input, it shall have the

same effect as <space>.

Lines beginning with other than the above characters are treated the same as lines beginning with a blank.

The ﬁrst character of a line is not printed. If any such lines appear, an appropriate diagnostic is sent to

standard error. This program forces the ﬁrst line of each input ﬁle to start on a new page.

(XPG4 only.) The action of the asa utility is unspeciﬁed upon encountering any character other than those

listed above as the ﬁrst character in a line.

To view the output of FORTRAN programs which use ASA carriage control characters and have them

appear in normal form, asa can be used as a ﬁlter:

a.out | asa | lp

The output, properly formatted and paginated, is then directed to the line printer. FORTRAN output pre-

viously sent to a ﬁle can be viewed on a user terminal screen by using:

asa ﬁle

EXTERNAL INFLUENCES

Environment Variables

LC_CTYPE determines the interpretation of text within ﬁle as single- and/or multi-byte characters.

LC_MESSAGES determines the language in which messages are displayed.

If LC_CTYPE or LC_MESSAGES 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, asa 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.
