IMHO it's the usual way, to implement work flow control. E.g. start/stop messages from a host program to a node (doing some calculations or waiting for an event to do something) naturaly contain no usefull data. The message itself (and possibly the message tag) is the information required by the node for operation. > 2) Why is the prototype for "pvm_catchout" commented out in "pvm3.h" ? I don't know. bye, Thomas F. -- ___________________________________________________________________________ ">. | Thomas Frank ; TUCZ-IMech ; Zi.
