Identifying the origin of the hiperspace

Some processors do not allow the hiperspace to start at address zero; these hiperspaces start at the address 4096. When you use DSPSERV CREATE, you can count on the origin of the data space staying the same within the same IPL. To learn the starting address, either (1) create a hiperspace of 1 block of storage more than you need and then assume that the hiperspace starts at 4096 or (2) use the ORIGIN parameter. If you use ORIGIN, the system returns the beginning address of the hiperspace to the location you specify.

An example of the problem you want to avoid in addressing hiperspace storage is described as follows:

Suppose a program creates a hiperspace of 1 megabyte and assumes the data starts at zero when it really begins at 4096. Then, if the program used the address zero in the hiperspace, the system abends the program.
