The pathname of a file to be read. If this parameter is omitted, stan-
dard input is read.
The asa command writes its input files to standard output, mapping
carriage-control characters from the text files to line-printer control
The first character of every input line is removed and, depending on the
character removed, an action performed on that character and the rest of
the line. If the character removed is:
The rest of the line is output without change.
0 A newline character is output, followed by the rest of the input line.
1 A form-feed character is output, followed by the rest of the input
+ The newline character of the previous line is replaced with a
carriage-return character, which is output, followed by the rest of the
input line. If + is the first character in the input, + has the same
effect as the space character.

trol characters) on a terminal:
2. To format the FORTRAN output of a.out and direct it to the printer:

The following environment variables affect the execution of asa:
Provides a default value for the internationalization variables that
are unset or null. If LANG is unset or null, the corresponding value
from the default locale is used. If any of the internationalization
variables contain an invalid setting, the utility behaves as if none of
the variables had been defined.
If set to a non-empty string value, overrides the values of all the
other internationalization variables.
Determines the locale for the interpretation of sequences of bytes of
text data as characters (for example, single-byte as opposed to multi-
byte characters in arguments and input files).
Determines the locale for the format and contents of diagnostic mes-
sages written to standard error.
Determines the location of message catalogues for the processing of
