Sharing Data Attributes

These attributes determine how the automatic data segment can be shared:

NONE

No automatic data segment is created.
SINGLE
A single automatic data segment is shared by all instances of the module. In this case, the module is said to have solo data. This keyword is the default for dynamic-link libraries.
MULTIPLE
The automatic data segment is copied for each instance of the module. In this case, the module is said to have instance data. This keyword is the default for applications.

These attributes refer to initialized global data. The automatic data segment is the physical segment represented by the group name DGROUP. This segment group makes up the physical segment that contains the local stack and heap of the application.
