volatile -

Calling sequence:
volatile(identifier [ ,identifier ... ])

Parameter:

identifier   --  any variable

Summary:

volatile prevents expressions occuring later on that contain arguments of
volatile from being entered into the internal associative memory.  Thus
the internal associative memory need not be deleted when these variables are
assigned new values. In this way the internal associative memory can be used
much longer and, thus, a much higher speed can be achieved.

If a variable is newly ???  embedded @@@ then volatile must be called
again to prevent expressions that contain this variable from being stored in
the internal associative memory. volatile is a kernel function.
