FOR1407S

System action
 If the unit is other than the error message unit,
the unit is no longer connected to a file. If neither the ERR nor
the IOSTAT specifier is present on the I/O statement, the condition
is signaled. If the condition is unhandled, the application is terminated.
 Qualifying
Data:  Only the basic set of four qualifying data for I/O conditions
as shown in Table 1. Within this
basic set, statement has a value of READ,
and parm_count has a value of 4.
 Permissible
Resume Actions:
 Name
Action Taken after Resumption

RN
The OPEN statement is not completed, and execution continues.

Programmer response
 Ensure that the VSAM key-sequenced data
set (KSDS) that you want to process is referenced by the file definition
(DD statement or ALLOCATE command).
 If you want to read from
a file that has records, then:  If the file referenced by the file definition is a base cluster,
that is, the file with the primary key, then ensure that is was successfully
loaded with records, either in a Fortran program or by a program written
in some other language.
If the file referenced by the file definition is a path for an
alternate index, then ensure that the Access Method Services BLDINDEX
command successfully built the alternate index after the base cluster
was loaded.

 If you want to start with an empty file and add records
to it in other than ascending sequence of the primary key, then change
the value of the ACCESS specifier to READWRITE. In this case the OPEN
statement processing simulates the loading of the file and deletes
all loaded records; then VSAM no longer considers the file to be empty.
 If
you want to load records into an empty file in the fastest way, follow
these steps:
 On the file definition (DD statement or ALLOCATE
command), provide the data set name of the file's base cluster, that
is, of the file with the primary key.
Execute an OPEN statement with a value of WRITE for the ACTION
specifier and a value of KEYED for the ACCESS specifier; either omit
the KEYS specifier or provide a KEYS specifier with a single start-end
pair that represents the position in the record of the file's primary
key.
Execute at least one WRITE statement to write the records; ensure
that you write the records in ascending sequence of the primary key.
Execute a CLOSE statement.

 After these steps, the file is available to be connected
using an ACTION specifier of either READ or READWRITE.
 If you
omit the DELIM specifier, then for list-directed formatting the character
values are written without delimiters, and for namelist formatting
the character values are surrounded by apostrophes.
