When is VSCORE used in Syncsort
The VSCORE option allows you to set the maximum amount of virtual storage below the 16-megabyte line that SyncSort can use for its working set.
The VSCORET option allows you to set the maximum amount of virtual storage below AND above the 16-megabyte line that SyncSort can use for its working set when SyncSort’s Dynamic Storage Management (DSM) facility is inactive.
When DSM is active, VSCORET is treated as an initial recommendation. The VSCORET value cannot be less than the value set in the VSCORE option.

REGION, VSCORE and VSCORET all refer to internal memory storage working space. The SORTWKxx files use external storage based on the SPACE parameter provided.
- internal memory is used first, in case the file is small
- SORTWKxx space is used when internal memory is insufficient
- tape is used for intermediate file storage on MAXSORT when SORTWKxx is insufficient
Thanks for the clarification. Sorry for my late reply.
I am searching the forum for other discussion on these parms to ask right questions. I am using SYNCSORT 22.214.171.124R
How do we calculate what is the Optimal value we can give for VSCORE and VSCORET?
How much internal storage is available. Is it above 16M or below 16M? This may be vary as i guess.
I saw that all REGION, VSCORE, VSCORET refer to internal memmory.
I wonder why do we need VSCORE and VSCORET separately.
Why dont we have single parameter like VSCORE, where we can say what is the value we want?
How does CORE=MAX differ from VSCORE and VSCORET? Does any parm has priority over other?
