HI, I am new to IDL so I am not sure what is the best solution for this problem. I am running a windows application that creates data on a shared drive. When the windows application is finished running I want to call idl to analyze the data. We are using IDL on ubuntu 64. I have googled and looked at the documentation on external programming and the only option for a distributed call is RPC. However RPC is only in unix and the lib_rpc.so does not have a windows version for the client or does it? What I am looking for is a way to call the idl rpc server from the windows client that I create. Is this possible, if not then is there another solution? Thanks Sheryl
