Dear THS, I think that what you are looking for is explained in the ENVI help system under: Getting Started With ENVI > Common Tools and Functions in ENVI > Working With ENVI Dialogs > Queuing ENVI Processes Try going to --> the ENVI main menu bar, select File > ENVI Queue Manager If you follow the ENVI help you will have a detail explanation on how to do what you would like to do. Cheers, Fernando

Hi Fernando, THS. I knew how to use the ENVI of the ENVI QUEUE Manager. But I would like to use IDL to call the Queued Procedures List. For example, there are procedures 1,2 3……in the Queued Procedures List. I hope to distribute this process in different computer. Can you help me? You just could show me the ENVI Queue Function. I will call this function. THS.
