I am using an output file in a program, i opened it in output mode and displayed the file status. I did not mention the DD name in the JCL and submitted the job.

The job got executed successfully and the file status displayed was 35.

Now i have coded WRITE statement for the same file and executed the job. Now the job abended with S0C4 and the file status displayed was 96.

Here I have displayed the file status before the WRITE statement.
If the program failed at WRITE statement then the file status should be 35 and abended. But it displayed 96 and abended.

Why the file status has been changed from 35 to 96 even before executing the WRITE statement?

Can somebody explain what happend in the background.


Thank you,
chintu

wow - I thought web pages with colours that horrible were outlawed in the 1980s after http://www.webpagesthatsuck.com first came out.

Since you did not provide any code, all we can do is guess, not explain. One possibility is that you attempted to use the buffer or its fields (the 01 level under the FD) which won't work when you get a 35 file status upon OPEN.

From an application programmer point of view, with WRTIE command, sytem assumes, file must be OPENed in OUTPUT, I-O or EXTEND mode (please NOTE: input mode is not included which will casue status 35) so with WRITE you get Status code 96 which means an OPEN statement with I-O or EXTEND phrase was attempted for an optional file, but no DD statement was specified for the file. And this is exactly what your case is.

this same question is posted in another forum (by a member who swears that this thread is not his).

therefore, this is a classroom exercise.
