[zFernand0]

To do:

• Add a new API (with its command) for: allocateLike
• Add a new API (with its command) for: copyDataset

System Test Scenarios: allocateLike

• Allocate PS A like PS B with recfm: F (and verify attributes)
• Allocate PS A like PS B with recfm: U (and verify attributes)
• Allocate PS A like PS B with recfm: V (and verify attributes)
• Allocate PS A like PS B with recfm: D (and verify attributes)
• Allocate PO A like PO B (and verify attributes)
• Allocate PO A like PS B (and verify attributes)
• Allocate PS A like PO B (and verify attributes)
• Allocate PS A (which already exists) like PS B
• Allocate PO A (which already exists) like PO B

System Test scenarios: copyDataset

• Copy PS A to new PS B (and verify attributes)
• Copy PS A to existing PS B (should fail without replace: true)
• Copy PS A to existing PS B (should pass with replace: true)
• Copy PO Member A.1 to new PS B (dataset attributes should match the PO, but with dsorg: PS)
• Copy PO Member A.1 to existing PS B (should fail without replace: true)
• Copy PO Member A.1 to existing PS B (should pass with replace: true)
• Copy PS A to existing PO with new member B.1
• Copy PS A to existing PO with existing member B.1 (should fail without replace: true)
• Copy PS A to existing PO with existing member B.1 (should pass with replace: true)
• Copy PS A to new PO with new member B.1 (dataset attributes should match the PS, but with dsorg: PO)
