avoid repeating trial type?

[akiko]

Hello,

I'm new to E-prime and trying to run a visual search experiment.
There are 12 possible locations that Target could appear, each target
location happens 3 times in 1 run. I'd like to randomize trials, but
target location should not repeat. Trials are listed in a List object
("trialList"), which has a Procedure called "search".

My most recent effort is to write the following InLine script at the
top of the "search" Procedure, but it doesn't work...

If TrialNum > 1 Then
       If lastTarLoc = c.GetAttrib("tarLocation") Then
			trialList.Terminate
       End If
End If

where "lastTarloc" is the target location of the previous trial (made
in the end of each trial) and "tarLocation" is the location of the
current trial. I'm guessing I have to use InLine and/or Label to do
this, but I don't know where to put it, and how it should be used.

If anyone knows how to do this, or knows of any example available
online, please let me know.
Thanks in advance!
Akiko
