Thanks > "DIAG 8" is simply a replica of the VM/370 (VM/SP, VM/ESA, z/VM) CP Interface. Simply look at the "z/VM CP Programing services" of the moment (the interface has been unchanged for the past 45 years or so). for example : https://www-01.ibm.com/servers/resourcelink/svc0302a.nsf/pages/zVMV7R1sc246272/$file/hcpb4_v7r1.pdf Look for DIAG 8 in that document... Hercules does the same (only the commands sent are of course hercules commands, not CP commands). --Ivan [Non-text portions of this message have been removed]
