Yes, you can do this with DCL. The OpenVMS DECnet documentation shows various simple examples using the task object and the TYPE command to trigger the execution of a DCL command procedure on a remote node. An example DCL command procedure that is rather more advanced than using the TYPE command as a trigger is included in the Ask The Wizard area: o http://www.hp.com/go/openvms/wizard/ For additional information on the OpenVMS Ask The Wizard (ATW) area and for a pointer to the available ATW Wizard.zip archive, please see Section 3.8. 8-8 DCL Details DCL does not include support asynchronous I/O, thus a predetermined protocol or a predetermined “turn-around” command sequence must be implemented in order to avoid protocol deadlocks-cases where both tasks are trying to write or both tasks are trying to read. The task that is writing messages to the network must write (or write and read) a predetermined sequence of messages, or it must write a message that tells the reader that it can now
