Retrieving Information About Loaded Modules

Both the CSVINFO and CSVQUERY macros return information about loaded modules. A loaded module is a load module that has been loaded into storage. Use CSVQUERY if you need information about a particular loaded module or if your program is running in access register (AR) mode. Use CSVINFO to obtain information about a group of loaded modules or when you want information about the loaded module associated with a particular program request block (PRB) or information that the CSVQUERY macro does not provide.

The following information is available only through the CSVINFO macro:

Whether the entry point is an alias created using the IDENTIFY macro.
The starting address of every extent and the number of extents for loaded modules with multiple extents. (CSVQUERY provides only the entry point address and the total module length.)
The load count, system count, and total use count for the loaded module.
The name of the major entry point, if the entry point is an alias.
The full entry point name for modules with names longer than 8 characters.

In addition to the information you request, the CSVINFO macro returns the file name for modules in the OpenMVS file system.
