Creating a hiperspace

To create a non-shared standard hiperspace, issue the DSPSERV CREATE macro with the TYPE=HIPERSPACE and HSTYPE=SCROLL parameters. The HSTYPE parameter tells the system you want a standard hiperspace. HSTYPE=SCROLL is the default. MVS™ allocates contiguous 31-bit virtual storage of the size you specify and initializes the storage to hexadecimal zeros. The entire hiperspace has the storage key 8. Because many of the same rules that apply to creating data spaces also apply to creating hiperspaces, this information sometimes refers you to Creating a data space.

On the DSPSERV macro, you are required to specify:

The name of the hiperspace (NAME parameter)
To ask DSPSERV to generate a hiperspace name unique to the address space, use the GENNAME parameter. DSPSERV will return the name it generates at the location you specify on the OUTNAME parameter. Specifying a name for a hiperspace follows the same rules as specifying a name for a data space. See Choosing the name of a data space.
A location where DSPSERV is to return the STOKEN of the hiperspace (STOKEN parameter)
DSPSERV CREATE returns a STOKEN that you can use to identify the hiperspace to other DSPSERV services and to the HSPSERV and DIV macros.

Other information you might specify on the DSPSERV macro is:

The maximum size of the hiperspace and its initial size (BLOCKS parameter). If you do not code BLOCKS, the hiperspace size is determined by defaults set by your installation. In this case, use the NUMBLKS parameter to tell the system where to return the size of the hiperspace. Specifying the size of a hiperspace follows the same rules as specifying the size of a data space. See Specifying the size of a data space.
A location where DSPSERV can return the address (either 0 or 4096) of the first available block of the hiperspace (ORIGIN parameter). Locating the origin of a hiperspace is the same as locating the origin of a data space. See Identifying the origin of a data space.
