By default, the file, assumed to be in ASCII format, is closed after reading,
and a subsequent <CODE>READ</CODE> command of the same file will start reading at the first record. If the
<CODE>\-CLOSEAFTER</CODE> qualifier is used, the file will be not closed after reading, so that the next
<CODE>READ</CODE> operation of the same file will begin reading at the next record. If the
<CODE>\CLOSEFIRST</CODE> qualifier is used, the file will be closed first and then reopened before
reading, so the <CODE>READ</CODE> operation will begin at the first record.</P>
<p>
By default, informational messages are displayed in the message area. If the
<CODE>\-MESSAGES</CODE>, qualifier is used, these messages will not be displayed.</P>
