M59, Environment reference not permitted for this ssvn

Approved for inclusion in a future M[UMPS] language standard.

Setting, Killing and referencing "nodes" in structured system variables is only allowed when the semantics for the operation in question are explicitly defined. Any reference to a ssvn, where an environment is specified, and no semantics are defined for the meaning of an environment in that context, will cause this error to occur.
