Edward Assuming you specify your USS message using the BUFFER operand, VTAM's USS logic and the TN3270E server logic will scan the message looking for text such as @@LUNAME in order to be able to insert, in this case, the secondary LU name - in the case of the TN3270E server, the selected APPL name. You are correct that VTAM's USS logic and the TN3270E server logic will not interfere with any other text including 3270 data stream orders.
Assuming you specify your USS message using the TEXT operand, VTAM's USS logic and the TN3270E server logic are actually required to construct the 3270 data stream around the provided text. Again there is variable substitution within the text provided in the TEXT operand - but no manipulation of text in orders - except for the sneaky action of OPT=BLKSUP which I mentioned in my previous post whereby multiple concatenated blank characters can be reduced to one. I think the OPT=BLKSUP function is there mainly for the operator message use of USS rather than the terminal user message use. You are not really encouraged to use the TEXT operand for the purposes of 3270 text and orders rather than just 3270 text but it works. The only snag I have found - other than the challenge of making it readable - is that OPT=BLKSUP action when trying to build a "set buffer address" for location 0.
