$ACM

   On Alpha and I64 systems, the $ACM service provides a common 
   interface to all functions supported by the Authentication and 
   Credential Management (ACM) authority.

   The caller must specify the function code and any applicable
   function modifiers and item codes for the requested operation.

   The $ACM service completes asynchronously; for synchronous
   completion, use the $ACMW form of the service.
