RS, It appears that VSAM can create a CA split without a CI split, see z/OS DFSMS Using Data Sets Chapter 9.
Also QED your examples before altering FSPC to zero. Regards.

I did the following: DEF CL ...FSPC(15 15) REPRO (20000 records) ALTER CL.DATA FSPC(0 0) REPRO (insert 500 recs) And I have 0 splits. BTW: I asked several persons and still have no answer: How it is possible to split CA without CI split ? Usually CA split is caused by inserting new CI - the CI is created because of CI split. Here, I have CA splits - do I *insert* new CIs ??? -- Radoslaw Skorupka Lodz, Poland P.S. THANK YOU GENTLEMEN FOR YOUR HELP -- BRE Bank SA ul.
