zFile for mvs dataset API to detect if it is archived

When querying an MVS dataset attributes using zFile, starting first with open the dataset or checking if it exists, it the dataset is archived/migrated, it would be automatically recalled.

This behavior is matching with ISPF behavior. (I think when system aut-recall is enabled.)

But the auto-recall could be an issue when running within an application like our product, where all processing and input mostly programmatically and should not require manual intervention. For example if the dataset archive resides on tape, the recall may requires manual interaction. Also, auto-recall is not always an desired option.

(Currently, we rely on the catalog vtocDirectory entry of the dataset's volser label marker dedicated for archived datasets to tell if it is archived.)

It's help if zFile could provide an API to detect first if the dataset is archived, or an option for the existing API for the option to allow auto-force-recall or not (if the dataset is archived).

Have it as low priority as we do have our work around, but it's great if zFile can offer that ability, it helps us to use the zFile API calls overall more smoothly and effectively in our code flow.

Thank you.
