Hello Kathie,

I'm not sure how you sent your request but it certainly confuses my mail 
program.  Lot's 
of attachments.

However, this one's easy.

Allocate the object in the usual way with ALCOBJ

Monitor for the exception message CPF1002
(Note that CPF1040 means you are hosed and should close down;
CPF1058 usually means that the object does not exist -- If you are particular 
you can 
retrieve the previous *DIAG message and if it is CPF0939 then the object does 
not exist)

Call the List Object Locks API (QWCLOBJL) to return a list of all jobs locking 
the object.

Iterate over the list performing an ENDJOB for each job you find.

You will need to use the user space APIs to create a space for the object list, 
and to 
retrieve the list contents.

Note that with pointer support in RPG and COBOL you can get a pointer to the 
space and 
iterate over the list directly rather than retrieving the space contents.

Regards,
Simon Coulter.

Hello to all. Can anyone help? I need to:
a) allocate a file exclusively ALCOBJ *EXCL...
b) if file is locked, see who has it? (workstation, job, user?)
c) blow that job away bye-bye
d) try allocation again, repeat for 5 minutes.... give up...

Thanks in advance;
Kathie Heeter
