Reading Structure Counts for a List Structure

Use IXLLSTC REQUEST=READ_STRCOUNTS to obtain the list structure count information on the maximum and in-use counts for a specific list structure.

The information for the structure that is returned in the answer area mapped by IXLYLAA includes:

The current in-use number of elements and maximum number of elements defined for the structure if data elements are defined for the structure.
The current in-use number of entries and the maximum number of entries defined for the structure.
The current in-use number of event monitor controls and the total number of event monitor controls defined for the structure if event monitor controls are supported by the structure.
The number of lock entries defined for the structure if the structure is defined as a serialized list structure.
