Loading External Files Into A List - Proper Set-up

[mcgree]

Thank you for the information.  Unfortunately, I think that I have
done what is outlined here, but it doesn't seem to be working.
Obviously, I know that I am doing something wrong, I'm just not quite
sure what.  Currently, I am just trying to get a practice program to
work rather than trying to tie together a full program and not be sure
where the errors are coming from.  To give a bit more detail, I am
using the E-BasicExample file from the included tutorials.  I have
added the following code to the script that is just before the list
named List1:
List1.LoadMethod = ebLoadMethodFile

List1.Filename = "MyTextFile.txt"

List1.Load

Additionally, I have created a .txt file that looks like the
following:
Weight	Procedure	Nested	Stimulus CorrectAnswer
1	TrialProc		Y	2
1	TrialProc		X	1
1	TrialProc		Y	2
1	TrialProc		X	1
1	TrialProc		Y	2
1	TrialProc		X	1

(In the text file the information within each cell is actually located
under the proper title, but the formatting is not working correctly
here.)  The only other information that I can think of that may be
helpful is that I have left the list blank with the exception of the
headers which are the same as the ones above.

I also tried two different ways to set up the rest of the code:  one
where I left the procedure under the list (normal setup) and one where
I moved it to the unreferenced objects section.  The first way
(basically just setting up the program normally) did not compile.
Instead, the "child item is a procedure" error popped up.  The second
way (moving the procedure to the unreferenced objects section) allowed
the code to be compiled; however when I actually run the program E-
Prime crashes completely.  Does anyone have any further thoughts on
why this may be or what I can do to fix this problem?  Thanks!
