In support of the Fortran I/O statement indicated by the message text, Language Environment executed an OPEN macro instruction. Either MVS™ or DFSMS/MVS detected the error indicated by system completion (abend) code completion-code and reason code reason-code.
If the error occurred during the execution of an OPEN statement, 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, parm_count has a value of 4.
Permissible Resume Actions:
| Name | Action Taken after Resumption |
|---|---|
| RN | The I/O operation is not completed, and execution continues. |
Ensure that the file definition (DD statement or ALLOCATE command) for the file you are using is coded correctly. If the the program uses dynamic allocation for the file, ensure that both the data set name given in the FILE specifier on the OPEN statement and the arguments on call to the FILEINF callable service are coded correctly.
For the meaning of system completion code completion-code and reason code reason-code, and for possible corrective actions, refer to z/OS DFSMS Macro Instructions for Data Sets.
