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