The communication network data manager system according to the invention provides remotely located host processors with the capability of moving sequential datasets, partitioned datasets, or members of partitioned datasets between them. Data is read directly from the source dataset, which may be on a tape or disk, and is written directly to the target dataset which also may be on a tape or disk. No intermediate storage is required for queuing or spooling the data being transferred. A data transfer request may be entered by the user through a user console operating under a menu driven display format. Alternatively, the data set transfer request may be generated by continuously running job applications through a batch interface.
