File Status Keys
Return Codes for Data Files & VSAM
This document provides a summary of the two-byte File-Status-Key (sometimes referred to as file return code or file status code) with a brief narrative for each code. For the COBOL environment if the FILE STATUS clause is specified in the FILE-CONTROL entry, a value is placed in the specified status key (the 2-character data item named in the FILE STATUS clause) during execution of any request on that file. The value indicates the status of that request. The value is placed in the status key before execution of any EXCEPTION/ERROR declarative or INVALID KEY/AT END phrase associated with the request.
The following tables contain file-status-key content that may be set by Micro Focus COBOL (Mainframe Express or Net Express) or an IBM Mainframe System (MVS, OS/390 or ZOS).
We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

The ANS/85 standard provides for a two-byte File-Status-Key. The first character of the File-Status-Key is known as status-key-1 and defines a group or category. The second character is known as status-key-2 additional detail.
Note: If status-key-1 is a nine (9) then status-key-2 is "implementer-defined". Many vendors take advantage of the x"00' to x'FF' (or 0-255) binary value. Therefore, the file status key may not always be a numeric value that is easy to display.
The combinations of possible values and their meanings are shown below with some comments where vendor additions or extensions may occur.
|Description by Group|
| || |
|0||Successful Completion or non-terminal condition that may be acceptable to continue processing. Refer to the section for Status-Key-1 being equal to "0" for additional information based on Status-Key-2.|
|1||End of File, attempting to read beyond the end of the file. Refer to the section for Status-Key-1 being equal to "1" for additional information based on Status-Key-2.|
|2||Invalid Key, an attemprt to access a file failed because the requested key is not available for processing. The error may be caused by an invalid key or the sequence of processing for a valid key. Refer to the section for Status-Key-1 being equal to "2" for additional information based on Status-Key-2.|
|3||Permanent Error, usually caused by a limit in the logical processing or a difference in the logical file definitions and the physical file. Refer to the section for Status-Key-1 being equal to "3" for additional information based on Status-Key-2.|
|4||Logic Error, a program is attempting a file access function in an improper sequence or beyond the capabilities of the physical file functions. Refer to the section for Status-Key-1 being equal to "4" for additional information based on Status-Key-2.|
|9||Implementor Defined, Many vendors take advantage of the x"00' to x'FF' (or 0-255) binary value. Therefore, the file status-key-2 may not always be a numeric value that is easy to display. Refer to the section for Status-Key-1 being equal to "9" for additional information based on Status-Key-2.|
The first character of the File-Status-Key is known as status-key-1; the second character is known as status-key-2. The combinations of possible values and their meanings are shown below.
1 & 2
|02||Indexed files only. Possible causes:
For a READ statement the key value for the current key is equal to the value of that same key in the next record in the current key of reference.
For a WRITE or REWRITE statement the record just written created a duplicate key value for at least one alternate record key for which duplicates are allowed.
|04||The length of the record being processed does not conform to the fixed file attributes for that file.|
|05||The referenced optional file is not present at the time the OPEN statement is executed.|
|06||Attempted to write to a file that has been opened for input.|
|07||Sequential files only. For an OPEN or CLOSE statement with the REEL/UNIT phrase the referenced file is a non-reel/unit medium.|
|08||Attempted to read from a file opened for output.|
|09||No room in directory or directory does not exist.|
|10||No next logical record exists. You have reached the end of the file.|
|12||Attempted to open a file that is already open.|
|13||File not found.
Also, check to see if the path to the file concerned exists (Micro Focus).
|14||Relative files only. The number of significant digits in the relative record number is larger than the size of the relative key data item described for that file.
Too many files open simultaneously (Micro Focus).
|15||Too many indexed files open (Micro Focus).|
|16||Too many device files open (Micro Focus).|
|17||Record error: probably zero length (Micro Focus).|
|18||Read part record error: EOF before EOR or file open in wrong mode (Micro Focus).|
|19||Rewrite error: open mode or access mode wrong (Micro Focus).|
|20||Device or resource busy (Micro Focus).|
|21||Sequentially accessed files only. Indicates a sequence error. The ascending key requirements of successive record key values has been violated or the prime record key value has been changed by a COBOL program between successful execution of a READ statement and execution of the next REWRITE statement for that file.|
|22||Indexed and relative files only. Indicates a duplicate key condition. Attempt has been made to store a record that would create a duplicate key in the indexed or relative file OR a duplicate alternate record key that does not allow duplicates.|
|23||Indicates no record found. An attempt has been made to access a record, identified by a key, and that record does not exist in the file. Alternatively a START or READ operation has been tried on an optional input file that is not present.|
|24||Relative and indexed files only. Indicates a boundary violation. Possible causes:
Attempting to write beyond the externally defined boundaries of a file.
Attempting a sequential WRITE operation has been tried on a relative file, but the number of significant digits in the relative record number is larger than the size of the relative key data item described for the file.
|30||The I/O statement was unsuccessfully executed as the result of a boundary violation for a sequential file or as the result of an I/O error, such as a data check parity error, or a transmission error.|
|32||Too many Indexed files opened. This can also happen when a sequential file is open for input and an attempt is made to open the same file for output.(Run Time System (RTS) message by Micro Focus).|
|34||The I/O statement failed because of a boundary violation. This condition indicates that an attempt has been made to write beyond the externally defined boundaries of a sequential file.|
|35||An OPEN operation with the I-O, INPUT, or EXTEND phrases has been tried on a non-OPTIONAL file that is not present. Trying to open a file that does not exist.
May need to map the COBOL file name to the physical file name. (Micro Focus, refer to the ASSIGN(EXTERNAL) directive).
|37||An OPEN operation has been tried on a file which does not support the open mode specified in the OPEN statement.|
|38||An OPEN operation has been tried on a file previously closed with a lock.|
|39||A conflict has been detected between the actual file attributes and the attributes specified for the file in the program.
This is usually caused by a conflict with record-length, key-length, key-position or file organization.
Other possible causes are:
1. Alternate indexes are incorrectly defined (Key length or position, duplicates or sparse parameters).
2. The Recording Mode is Variable or Fixed or not defined the same as when the file was created.
3. For files with variable-length records the minimum and maximum record lengths for the actual file may not match the minimum and maximum record lengths used by the program
|41||An OPEN operation has been tried on file already opened.|
|42||A CLOSE operation has been tried on file already closed.|
|43||Files in sequential access mode. The last I/O statement executed for the file, before the execution of a DELETE or REWRITE statement, was not a READ statement.|
|44||A boundary violation exists. Possible causes:
Attempting to WRITE or REWRITE a record that is larger than the largest, or smaller than the smallest record allowed by the RECORD IS VARYING clause of the associated file.
Attempting to REWRITE a record to a file and the record is not the same size as the record being replaced.
|45||An attempt has been made to REWRITE a record to a file, and the record is not the same size as the record being replaced.
(Micro Focus) For line sequential files this refers to the physical size of the record, that is after space removal, tab compression and null insertion. In this case, the physical size of the new record is allowed to be smaller than that of the record being replaced.
|46||A sequential READ operation has been tried on a file open in the INPUT or I-O mode but no valid next record has been established.|
|47||A READ or START operation has been tried on a file not opened INPUT or I-O.|
|48||A WRITE operation has been tried on a file not opened in the OUTPUT, I-O or EXTEND mode or on a file open I-O in the sequential access mode.|
|49||A DELETE or REWRITE operation has been tried on a file that is not opened I-O.|
The first character of the File-Status-Key is known as status-key-1. If status-key-1 is equal to 9 then status-key-2 is a one byte, binary value as defined in the following table.
|9000||00||No further information.|
|9001||01||Insufficient buffer space. Could also indicate an out of memory situation.|
|9002||02||File not open when access tried.|

This can also be cause when a physical line sequential file (ASCII/Text) is being read as a sequential file and the directive SEQUENTIAL(LINE) is not set (Micro Focus).
|9019||13||Rewrite error: open mode or access mode wrong.|
|9020||14||Device or resource busy.|
