Classification: CPC G | IPC G

Claim 5:
6. A computer-implemented method comprising:
receiving, from high level language code running on a Mainframe operating system of a Mainframe computer, a request for writing a data set to a disk in AWSTAPE format, the disk mounted on the Mainframe computer, wherein the request for writing the data set is a request to copy the data set from an object storage connected over TCP/IP, the object storage comprising information to be exported;
locating, from the high level language code, locating a mapping object within the object storage;
allocating, from the high level language code running on the Mainframe operating system, the data set in the AWSTAPE format;
retrieving, from the high level language code and using the mapping object, data chunks from the object storage into the data set, the data chunks including blocks of data;
providing, by the high level language code and from the data chunks, block by block from the blocks of data, tape header VOL1, data set headers HDR1, HDR2, file content, and data set trailers EOF1, EOF2 from the high level language code to an assembly program;
writing, by the assembly program, block by block, the tape header VOL1, the data set headers HDR1, HDR2, the file content, and the data set trailers EOF1, EOF2 to the data set on the disk; and
closing the data set.
