Mark, You need a real CTC with both ends connected to the same system. You ACTIVATE ISLINK for one end on the first-level system. You ATTACH or DEDICATE the other end on first level to the virtual machine for the second-level system. You then ACTIVATE ISLINK for that device on the second-level system.

I've used VCTC between guests for years. What I needed, but apparently is not supported is a VCTC, connecting CP to a virtual machine for ISFC links.

On first level, define one Virtual CTC (FCTC, SCTC) into TCPIP (or another capable machine) to connect to second level VM. On second level VM, define and couple the Virtual CTC to first level TCPIP before his IPL (COMMAND into Directory is a good place to set it). After the IPL, DEDICATE the CTC (the second level thinks it is a REAL CTC) to his TCPIP machine. Done, you have the two TCPIPs connected by CTCs... Work fine also for VTAM machines, RSCS, PVM, zOS and so long... ______________________________________________ Clovis Pereira Error!
