The function uses `dosubl()` to run the `table.fileinfo` action, for the
specified library, filtering for `*.sashdat` tables.
IMPORTANT NOTE - The results are cached in a WORK table (&outprefix._&lib).
If that table already exists, it is queried instead, to avoid the
dosubl() performance hit.
To force a rescan, just use a new `&outprefix` value, or delete the table(s)
before running the function.
Results are cached in a WORK table (&outprefix._&lib). If that table
already exists it is queried directly to avoid the dosubl() overhead.
To force a rescan, use a new `&outprefix` value or delete the cache
table before calling.
@param [in] libds library.dataset
@param [in] usecache= (1) Set to 0 to rebuild the cache
@param [out] outprefix= (work.mfv_existsashdat)
Used to store current HDATA tables to improve subsequent query performance.
This reference is a prefix and is converted to `&prefix._{libref}`
