The following environment variables may be set by the user:
Determines the clobber behaviour. 0 implies that datasets may not be
overridden, whilst 1 implies otherwise.

- 1, high

Determines the number of rows selected when iterating over a table. Any
positive integer value is allowed.
The DAL can write table columns (to the underlying FITS file) either in a

row-by-row, but setting the environment variable SAS_COLUMN_WISE ensures
the column-by-column method is used.
