Which drive does SAS WORK go to now? This will tell you where:</P> <PRE><CODE class=" language-sas">proc options option = work; run;</CODE></PRE> <P>&nbsp;</P> <P>Typically you point to a different SAS WORK space in your SAS config file but it can be done as an option in the SAS batch command</P> Wed, 09 Feb 2022 19:21:31 GMT https://communities.sas.com/t5/SAS-Programming/Direct-I-O-traffic/m-p/795299#M255072 SASKiwi 2022-02-09T19:21:31Z
