What SDSF is doing here is using the MGCRE service with the CART parameter (the 
"CART" is the command response token) to send the operator command to an EMCS 
console. 

The expectation in most cases is that the code that eventually executes in 
whatever ASID because of the operator command looks at the CIB and sees that 
there is a CART present and then uses the CART=CIBXCART specification on the 
WTOs that writes messages containing the operator command response. This allows 
the EMCS that SDSF has established to wake up and get the message(s).

Not all software products use CARTs on their WTOs and there may be 
architectural reasons why some base z/OS components do not use CARTs either. To 
cater for this, SDSF must establish a timer so it can give up waiting - hence 
the setting in the SDSF options.

Subject: NO RESPONSE RECEIVED

When you issue an operator command from SDSF (/S proc or /D IPLINFO, for
example) what determines whether SDSF displays "NO RESPONSE RECEIVED" in the
upper right or displays the messages that result from the command's being
issued? /S myproc, for example, results in WTO messages being issued within
less than a tenth of second but SDSF says NO RESPONSE RECEIVED. 

>From SDSF's point of view, what is a "response"? I've looked at QEDIT and
CIB and I don't see a way to "respond" as opposed to just "doing something."

Thanks,

Charles Mills
