Response time-outs

[David McFarlane]

Yes, you could do this with a bit of inline script.  Put the script 
at some time after the response (or rather, non-response), might as 
well put it just before the end of your procedure.  Let's suppose you 
ask for a response to a Slide object called ProbeSlide.  Then your 
script might look like this (note the comment in the script fragment 
-- *always* comment this sort of thing in your script so that the 
next person (who might be you in another year) will not wonder why 
you put this script here):

' Change empty response to "NA" for greater compatibility with R:
If ProbeSlide.RESP = "" Then
     ProbeSlide.RESP = "NA"
     c.SetAttrib "ProbeSlide.RESP", ProbeSlide.RESP
End If

Note that I changed both the .RESP property of ProbeSlide and the 
context attrribute "ProbeSlide.RESP".  If you know what you are doing 
then you only have to change one or the other (only the attribute 
matters for the data log), but doing both protects you from script 
that E-Studio may generate automatically later in the procedure.
