     A few other system tasks supported by NCV:
     
     $deposit is supported, though I'm not sure this is a good thing to be in
     the standard. The behavior of when the deposited value gets overwritten
     is not well defined, nor can it really be defined, since it depends on
     the internals of evaluation and updating in the particular simulator.
     
     $disable_warnings and $enable warnings, for selectively turning on and
     off timing and trireg decay warnings in parts of the design.
     
     $system, for executing OS command lines. This may not be a good thing to
     standardize, since any design using it is inherently not portable between
     OSes with different command syntaxes.
