Reads a single line from an open sequential file and assigns it to a String variable.
string = file.LineInputString()
Data read with LineInputString is usually written from a file with LinePrint.
The LineInputString statement reads from a file one character at a time until it encounters a carriage return (Chr(13)) or carriage return–linefeed (Chr(13) + Chr(10)) sequence. Carriage return–linefeed sequences are skipped rather than appended to the character string.
