It does this all itself - not using any IBM tools. So there is no question of "supported system". The only question is "which virtual supported system" do you wish to emulate? It can emulate a 2314, a 3330, a 3390. It's up to me to specify "user requirements". > then use 3390 with a block size compatible with the smallest > track size you have to load to. If it's 3390 to 3390, I'd use 32K. It will almost certainly be 3390 to 3390, but I see no reason not to use a blocksize of 6144 - IBM products are normally/often/ traditionally distributed with such a "universal block size". And then yes - it could be restored even to a 2314. Although I am still unsure about something. Is it correct that an unloaded 3390-residing load module on a modified MVS 3..8 system with a block size of 6144 can be loaded to say a 3330 on an unmodified MVS 3.8 system (that knows nothing about 3390) because the required device characteristics are self-contained in the IEBCOPY unload format and IEBCOPY can thus deal with unknown devices?
