COBRT021 - COBRT040

• COBRT021 File is a directory (Fatal)
  You have tried to WRITE to a directory instead of to a file.
• COBRT022 Illegal or impossible access mode for OPEN (Recoverable)
  The mode in which you are trying to open a file violates the General Rule of COBOL for that type of file; for example you might have opened a line sequential file in the I-O mode.
• COBRT023 Illegal or impossible access mode for CLOSE (Recoverable)
  The mode in which you are trying to close a file is not possible for that type of file.
• COBRT024 Disk input-output error (Recoverable)
  You might have performed a read after a WRITE, or there might be either a verification failure or a parity error.
• COBRT025 Operating system data error (Fatal)
  You are trying to set up terminal characteristics for a device which is not a terminal.
• COBRT026 Block I-O error (Fatal)
  An error has occurred while you are trying to access a disk. This could be the result of a corrupt disk.
• COBRT027 Device not available (Recoverable)
  You are trying to access a device which either is not attached to your machine or if attached is not online.
• COBRT028 No space on device (Fatal)
  You have tried a file operation such as WRITE for which insufficient space is available on your disk.
• COBRT029 Attempt to delete open file (Recoverable)
  You have tried to perform a DELETE FD operation on an open file.
• COBRT030 File system is read-only (Recoverable)
  The file system which you are using is read-only, which effectively means that it is write-protected. You have tried to change a file in some way, for example you might have tried to WRITE to a file or to DELETE information in it.
• COBRT031 Not owner of file (Recoverable)
  You are trying an operation on a file but the file's owner has not given you the necessary permission for that operation. You could for example be trying to alter the access modes for a file, which only the file's owner can do.
• COBRT032 Too many indexed files, or no such process (Recoverable)
  You have tried to open an indexed file but the number of files that you currently have open is the system limit.
• COBRT033 Physical I-O error (Fatal)
  You have a hardware error of some type. Perhaps you have not put a disk in the relevant drive or you might have tried to WRITE to a disk but the processor detected hardware interface has failed.
• COBRT034 Incorrect mode or file descriptor (Recoverable)
  You are either trying to write to a file which is open for read purposes only, or read a file which is open for write purposes only.
• COBRT035 Attempt to access a file with incorrect permission (Recoverable)
  You are trying a file operation which you do not have sufficient permission to achieve. For example you could be trying to write data to a file which has been set up with the read attribute only.
• COBRT036 File already exists (Recoverable)
  You are trying an inappropriate operation on an already existing file.
• COBRT037 File access denied (Fatal)
  Your attempt to access a file has been denied by the operating system. You might have tried to write to a write-protected file or you could have tried to read from an output device.
• COBRT038 Disk not compatible (Fatal)
  You have tried to access a disk that is incompatible with the current version of your operating system. This could be because it was created under a previous version of the system or it could have been created under a completely different operating system. You would also receive this error if you tried to load a disk with a name that clashed with a disk that was already loaded.
• COBRT039 File not compatible (Fatal)
  You have tried to access a file that is not compatible with the structure of files under the current release of your software. This could be because the file was created either under a different operating system or under a previous version of your current system.
• COBRT040 National Language initialization not set up correctly (Fatal)
  You have tried to use the additional language variants, but the environment or side file that is required to set up the language either has not been set up correctly, or does not exist, or is invalid.
