Kenneth,

VSM will not allocate "normal" storage from LSQA. REGION=0M sets the 
highest useable User Region address to the 2GB boundary (see the LDA), but 
when the User Region top actually hits the bottom of the LSQA storage, you 
stand to get an 878-10 type abend. I have seen it happen in many JVM 
abends.

Regards.

mike

Subject
REGION=0M and LSQA






I wish to ask the group on the pitfalls of coding REGION=0m.  Is it true 
that if more storage is needed up to the region cap, VSM will 
allocate from LSQA? 

Thanks, 

Kenneth J. Kripke
