The existing versions of the CL/1 Server for VMS are 1.0 and 1.1, which are compatible only with AT VMS 2.0, 2.0.5, 2.0.6, and 2.1; not 3.0.
The Data Access Language Server for VMS version 1.2 is shipping as part of DEC PATHWORKS (formerly LanWORKS) for Macintosh, which includes AppleTalk for VMS 3.0. If purchased separately, DAL 1.2 is supported under ATVMS 3.0 OR any one of 2.0, 2.0.5, and 2.0.6 (but not 2.1).
Note: The DAL Client requires a DAL Server. It will not connect successfully to an existing CL/1 Server, and a CL/1 Client will not work with a DAL Server. DAL Server/Client 1.2 will replace existing CL/1 Server/Client 1.1. The released version of PATHWORKS for Macintosh includes DAL Server/Client 1.2.
PATHWORKS for Macintosh (including AppleTalk for VMS 3.0) has been shipping since early autumn 1990 as has DAL Server/Client 1.2.
