<paragraph id="par_id3145749" role="paragraph" xml-lang="en-US"> <emph>FileNumber:</emph> Number of the file that contains the data that you want to read. The file must be opened with the Open statement using the key word INPUT.</paragraph>
<paragraph id="par_id3150011" role="paragraph" xml-lang="en-US"> <emph>var:</emph> A numeric or string variable that you assign the values read from the opened file to.</paragraph>
<paragraph id="par_id3159153" role="paragraph" xml-lang="en-US">The <emph>Input#</emph> statement reads numeric values or strings from an open file and assigns the data to one or more variables. A numeric variable is read up to the first carriage return (Asc=13), line feed (Asc=10), space, or comma. String variables are read to up to the first carriage return (Asc=13), line feed (Asc=10), or comma.</paragraph>
<paragraph id="par_id3146984" role="paragraph" xml-lang="en-US">Data and data types in the opened file must appear in the same order as the variables that are passed in the "var" parameter. If you assign non-numeric values to a numeric variable, "var" is assigned a value of "0".</paragraph>
<paragraph id="par_id3156442" role="paragraph" xml-lang="en-US">Records that are separated by commas cannot be assigned to a string variable. Quotation marks (") in the file are disregarded as well. If you want to read these characters from the file, use the <emph>Line Input#</emph> statement to read pure text files (files containing only printable characters) line by line.</paragraph>
<paragraph id="par_id3147349" role="paragraph" xml-lang="en-US">If the end of the file is reached while reading a data element, an error occurs and the process is aborted.</paragraph>
