Copy file from Tape to Disk

Copying a file from tape to disk is common in mainframe environments. Data is archived on tape and later retrieved to disk for processing or analysis. In this operation, the tape dataset is used as the input (SYSUT1), and the disk dataset is used as the output (SYSUT2). Tape datasets require specific handling, such as specifying the UNIT as TAPE and providing a tape label identifier (LABEL) if necessary.

Practical Example -

Scenario - Copy a dataset from a tape volume to a new file on disk.

Input PS File on tape - MATEPK.IEBGENER.INPTAPE
