Have you tried

OVRDBF FILE(F) FRCRATIO(1)  ?

This should force a write for each record.  It may hurt performance a bit if
lots of records are involved.

Here is the help text:

                Records to force a write (FRCRATIO) - Help

 Specifies the number of insert, delete, or update operations that can
 occur on records before those records are forced into auxiliary
 (permanent) storage.  If this physical file is being journaled, either a
 large number or *NONE should be used.  *NONE may cause long
 synchronization of the journal and physical files.  More information on
 this parameter is in the CL Reference information in the AS/400
 Information Center at http://www.ibm.com/as400/infocenter, Appendix A.
 More information on journal management is in the Backup and Recovery
 book, SC41-5304.

 This parameter overrides the force-write ratio specified in the database
 file, in the program, or in other previously issued OVRDBF commands.

Hi every one.

I need some help (any would be thank) to fix a problem I have when writing
into a file from 2 diferent subprograms calles from the same main program
on the same execution.

I have a main program (A) calling 2 programs (B and C). They are all cobol
programs and A is called fron a main CL program. There is a file (F) 800
positions long that would recive information from programs B and C.



The sistem works this way:

A starts and begin the cicle:
- A calls B. B opens file F and writes 2 records and goes back.
- A calls C. C opens file F,  writes 8 records to file F and goes back.
- A calls B again and B writes 2 new records to file F and goes back.
the cicle terminates and A finishes.

File F is never closed but at the end when probrams B and C are called and
should never be, cause there could be 1000's of cicles like this in a
single execution.

When the file is browsed I find the 'C' records first and all the 'B'
records together at the end.

I think the records order has somthing to do with the buffer size and the
usage of a diferent path to acces F for each program B and C.

Is there any way to force the order of the records as they were writen?
