Intermix of Duplicated And Non-duplicated Datasets On Multiple Files

Updating of both duplicated and non-duplicated records on multiple disk files can be done from a single source input.

In a system having dual files A and B containing redundant data, there may be cases where there can be unique data for file A and unique data for file B. When the unique data is to be updated, the update program can test the hardware to determine which file it is running on. It can then test the input data identifier. If the identifier is for one or the other of the files, it must be directed only to that file. If the identifier is for the file running in the hardware, then writing is allowed. If not, the input data is bypassed and the data resident in the file is not overlayed. If the identifier indicates that the data is to be written into both files, then writing proceeds irrespective of which file is running in the hardware. There can als an option to write the B Side input in the A Side hardware with a warning message.
