Take a look in the joblog and you will probably find additional error codes issued that will help to explain the situation.

Hello all,

I’ve been working for a long time on mainframes under z/OS and z/VSE
operating systems. Now, I’m exploring the midrange side while starting to
work on a iSeries (formerly AS-400) computer under OS/400 coding my firsts
COBOL 400 programs.

I have a problem when running a new program that reads a DATABASE file
which contains an agenda and shows it on a screen using a subfile. I took
the example from a blog ([1]AS400: Creación de un Subfile - Cobol

The problem I have is that when I OPEN TAGENDA the open fails with File
Status = 30.

I looked for the explanation of this error but it isn’t clear enough to

Could any of you give me any guidance about how to fix it?
