The Wait command stops execution until one or more remote compute nodes are finished processing.  

When node is given as a parameter, the current process will wait until that specified node is finished. If the given node was finished prior to calling Wait (or never started a job), Wait will return immediately.

When no parameters are given, the call to Wait will block until all compute nodes are finished processing.

The Wait command is intended to be called by the main Maple session, not the compute nodes. See the Barrier command for information about syncing up remote compute nodes.

The Wait command is only available in local Grid mode.
