If you want to connect an unnamed file, ensure that the value given for the the unit number does not exceed the smaller of either 99 or the highest unit number allowed at your site.
If you want to connect a named file, add a FILE specifier to the OPEN statement and provide either a ddname or a data set name, the latter preceded by a slash ( / ).
If you want the OPEN statement to refer to an existing connection between a unit and a file (so that you can use one or more of the BLANK, CHAR, DELIM, and PAD specifiers to change the properties of the connection), then ensure that the unit is connected to a file before executing the OPEN statement.
