The HSMAXSPC= option
specifies the maximum number of physical hiperspaces (each of which
has the size specified by the HSLXTNTS= option) that can be allocated
in a single SAS session.
The value that you specify
must be in the range 0 to 2,147,483,647. If you specify zero, SAS
allocates 1,920 blocks of VIO for the library. Check with your system
administrator for any site-specific maximum number of hiperspaces
that you can have.
