$ACMW

   The $ACM service provides a common interface to all functions
   supported by the Authentication and Credentials 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.
