Is an If...then... by cycle possible?

E-Prime is a great system for using existing programming skills to build 
programs for psychology experiments, but it is a lousy system for first 
learning how to program.  For that I recommend taking a regular course
in any established object-oriented computer language such as 
VisualBasic, Python, JavaScript, or C++.  But enough editorial, on to 
your question (which was very nicely laid out)...

Perhaps.  As you have noticed, your E-DataAid files have a column or 
"attribute" showing a cycle count for each List, e.g., 
"TrialList.Cycle".  Naturally, you want to know if you can use this 
attribute within your program.  Well, like most any E-Prime attribute, 
the list cycle count is available through the GetAttrib method of the 
Context object (see the online E-Basic Help for details), e.g.,

If c.GetAttrib("TrialList.Cycle") Then ...

But I have not explored this very far, and the cycle attribute for your 
list may not be available at every phase of your program.  So...

Even if you can do this with the cycle count, doing it with a variable 
may offer some advantages.  I cannot show you the entire way, but first 
you need to set up a global variable.  To learn how to do that please 
work through the "Using E-Basic" chapter of the User's Guide that came 
with E-Prime, especially 4.3.4 ff.  You should be able to take it from 
there.
