Using a hiperspace as a data-in-virtual object z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |
|
Your program can identify a non-shared standard hiperspace as a temporary data-in-virtual object, providing no program has ever issued an ALESERV ADD for the hiperspace. With the hiperspace as the object, the window must be in an address space. Use the hiperspace for temporary storage of data, such as intermediate results of a computation. The movement of data between the window in the address space and the hiperspace object is through the DIV MAP and DIV SAVE macros. The data in the hiperspace is temporary. Figure 1 shows an example of a hiperspace as a data-in-virtual object. Figure 1. A Standard hiperspace as a data-in-virtual object
When the hiperspace is a data-in-virtual object, data-in-virtual services transfer data between the hiperspace object and the address space window. In this case, your program cannot use the HSPSERV read and write operation. |
