Effect
The CRE can report this error when it closes your input file. All other instances are language and
application dependent.
Recovery
If the error was caused by a read request from your program, correct your program. You might
need to ensure that your program handles conditions that are beyond your control such as losing
a path to the device. Also refer to error handling in this manual and in the language manual for
the routine in your program that detected the error.
If the error was caused by a read request from the CRE, consult your system administrator.
If the error was caused during program initialization, specify an acceptable input file when
executing your program.

Recovery
If the error was caused by a write request from your program, correct your program. You might
