Trying to run your example and getting the following error:

Error Occurred!
Sorry, but your query caused an error in the SurferScript 
template that services this request-- the status is: 
Variable Value 
RetCode -1 
FailComponent TEACTION CONNECT 
FailMessage Unable to connect to group LU_GROUP_1--rc=-7 
(For connection type *ANY no target host specified...) 
FailSection cfsurfer.booklist 
SessionKey  
ScreenID 

Very sorry--change in the install program caused this 
problem.

Please edit the \screensurfer\hostserver\cfsurfer.stml file, 
and look for the following line:

<TEDECLARE VAR Server.YaleDemoGroup Text 20 
data="LU_GROUP_1">

Change it to:

<TEDECLARE VAR Server.YaleDemoGroup Text 60 
data="LU_GROUP_1:TN3270:orbis.yale.edu">

Then, use the DevCenter to Compile (red arrow button in the 
logo area), which will activate this change.

Err, actually, of course this error was introduced on 
purpose so you could learn how to edit a template file, then 
recompile to activate the change...(?)
