Map at_cascade Shared Memory Names
##################################

Prototype
*********
{xrst_literal ,
   # BEGIN_DEF , # END_DEF
   # BEGIN_RETURN , # END_RETURN
}

Purpose
*******
The mac Darwin system has a limit on the length (in characters) of
shared memory names. This routine returns a mapping of the shared memory
name that is short enough to work on the current system.
