I suspect the reasons are ancient and not relevant anymore. Maybe practical experience as result of initiator fragmentation. I don’t understand: " set the result as limit below
set the result minus 96K as size below. " You can probably set up modern rules, depending on your available storage, like: if regionsize < 512M then set regionsize=512M else allow requested regionsize.

Part of the logic flow is: If REGION=x is coded in the JCL and x <16M or x = 0M then do add 96K to REGION limit below Q1: Why 96K? end else do Take the region size below from LDASIZA substract LDAHIAL substract 384K Q2: Why 384K set the result as limit below set the result minus 96K as size below. Q3: Why 96K? end If anybody has an idea about Q1, Q2 oe Q3, i would be most grateful.
