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.

table before calling.
