- SCOPE=SINGLE data spaces
All programs can create, use, and delete SCOPE=SINGLE data spaces. Your program would use data spaces in much the same way as it uses private storage in an address space.
- SCOPE=ALL and SCOPE=COMMON data spaces
Supervisor state or PSW key 0 - 7 programs can create, use, and delete data spaces that they can share with other programs. These data spaces have uses similar to MVS™ common storage.
To protect data in data spaces, the system places certain restrictions on problem state programs with PSW key 8 - F. The problem state programs with PSW key 8 - F can use SCOPE=ALL and SCOPE=COMMON data spaces, but they cannot create or delete them. They use them only under the control of supervisor state or PSW key 0 - 7 programs. This chapter assumes that the data spaces your program creates, uses, and deletes are SCOPE=SINGLE data spaces.
