Hi, Chris, Many thanks for the hints.
RCEAFC is exactly the value which is shown by the RMF-Monitor II-Menues in TSO.
I will try the SYSEVENT-call and look, what it returns and compare it with the other values.

To find out how the system thinks it is doing, look at SYSEVENT STGTEST in the Authorized Assembler Reference manual. That gives you back two values, three actually, but now the third is the same as the second. These values are only updated once a second. There is also the RCEAFC that has the available frame count. The RCEPOOL has the total number of frames for the LPAR. The RCEBELPL has the below the line number and RCEABVPL has the above the line number. You have to derive the above the bar (64-bit) pages. ABAR = RCEPOOL - RCEABVPL - RCEBELPL OK, the first value from the SYSEVENT is basically the available frame count minus a machine configuration derived constant. The second value is basically the number of what I call under-utilized frames. If a frame has a UIC count greater than the system target UIC, then it is a candidate for stealing. This value includes the first value frame count. IBM has been tight lipped about how they currently derive the values returned by SYSEVENT STGTEST, so my comments are based on old knowledge and current observations and taking my best guess. The other variable mentioned are right from the System Data Areas manuals. Christopher Y.

With RMF-monitor-II-snapshot this value is not provided. Are there any systemcalls or controlblock-chains to be looked for to get this value ? I would appreciate any hints.
