Great to see that SAS 9.4 M4 has made it possible to discover and change the current working directory. The need for this has been obvious for so long that the bodged workaround with X was documented. Unix has been able to do this from the beginning (pre-1986) and MS-DOS from very early. What took so long? And what is the DLG part of the name? I would have found something like CHGWDIR easier to remember, if you must limit to 7 characters. This kind of obscurity will not convert new users to SAS.
