InStream Data Type
Version: Available or changed with runtime version 1.0.
Is a generic stream object that you can use to read from or write to files and BLOBs. You can define the internal structure of a stream as a flat stream of bytes. You can assign one stream to another. Reading from and writing to a stream occurs sequentially.
