</a>DESCRIPTION</h4><blockquote>The<i>asa</i>utility will write its input files to standard output, mappingcarriage-control characters from thetext files to line-printer control sequencesin an implementation-dependent manner.<p>The first character of every line will be removedfrom the input, and the following actions will be performed:<p>If the character removed is:<dl compact><dt>space<dd>The rest of the line will be output without change.<dt><b>0</b><dd>Anewline characterwill be output, then the rest of the input line.<dt><b>1</b><dd>One or more implementation-dependent characters that causesan advance to the next page will be output, followed by the rest ofthe input line.<dt><b>+</b><dd>Thenewline characterof the previous line will be replaced with one or more implementation-dependentcharacters that causes printing to return to column position 1,followed by the rest of the input line.If the"+"is the first character in the input, it will have the same effect asthe space character.</dl><p>The action of the<i>asa</i>utility is unspecified upon encountering any character other thanthose listed above as the first character in a line.</blockquote><h4><a name = "tag_000_000_061"> </a>OPTIONS</h4><blockquote>None.</blockquote><h4><a name = "tag_000_000_062"> </a>OPERANDS</h4><blockquote><dl compact><dt><i>file</i><dd>A pathname of a text file used for input.If no<i>file</i>operands are specified,the standard input will be used.</dl></blockquote><h4><a name = "tag_000_000_063"> </a>STDIN</h4><blockquote>The standard input will be used only if no<i>file</i>operands are specified.See the INPUT FILES section.</blockquote><h4><a name = "tag_000_000_064"> </a>INPUT FILES</h4><blockquote>The input files must be text files.</blockquote><h4><a name = "tag_000_000_065"> </a>ENVIRONMENT VARIABLES</h4><blockquote>The following environment variables affect the execution of<i>asa</i>:<dl compact><dt><i>LANG</i><dd>Provide a default value for the internationalisation variablesthat are unset or null.If<i>LANG</i>is unset or null, the corresponding value from theimplementation-dependent default locale will be used.If any of the internationalisation variables contains an invalid setting, theutility will behave as if none of the variables had been defined.<dt><i>LC_ALL</i><dd>If set to a non-empty string value,override the values of all the other internationalisation variables.<dt><i>LC_CTYPE</i><dd>Determine thelocale for the interpretation of sequences of bytes of text data ascharacters (for example, single- as opposed to multi-byte charactersin arguments and input files).<dt><i>LC_MESSAGES</i><dd>Determine the locale that should be used to affectthe format and contents of diagnosticmessages written to standard error.<dt><i>NLSPATH</i><dd>Determine the location of message cataloguesfor the processing of<i>LC_MESSAGES .</i></dl></blockquote><h4><a name = "tag_000_000_066"> </a>ASYNCHRONOUS EVENTS</h4><blockquote>Default.</blockquote><h4><a name = "tag_000_000_067"> </a>STDOUT</h4><blockquote>The standard output will be the text from the input

following command:<pre><code>asa file</code></pre>permits the viewing of<b>file</b>(created by a program using FORTRAN-style carriage control characters)on a terminal.<p>The following command:<pre><code>a.out | asa | lp</code></pre>formats the FORTRAN output of<b>a.out</b>and directs it to the printer.</blockquote><h4><a name = "tag_000_000_075"> </a>FUTURE
