help needed

Hi Asma,

This inline uses a for...next loop in order to populate the recall
list with items that were not presented in the studyproc. Items that
have been sampled in the studyproc are set to 1 in the initial
studyproc phase. In the complete recalllist inline, variables are
first set to numbers (Dim i as integer and Dim unsampled as integer).
The code seraches for an item in the list which is not 1 (<> 1) using
Loop Until StudyList.GetAttrib(unsampled, "Sampled") <> "1". Once
found, the sample is then marked as sampled in the studylist using
StudyList.SetAttrib unsampled, "Sampled", "1". It is then added to the
recall list which will be used in the second phase of the experiment
using counter = counter +1 then RecallList.SetAttrib counter, "Word",
StudyList.GetAttrib (unsampled, "Word") with the correct answer for
the unsampled item set to 2 using RecallList.SetAttrib counter,
"CorrectAnswer", "2". Next i means that the for i = 0 to 1 is repeated
until the recalllist is populated with unsampled itmes making up the
quota left over from the sampled items. Once populated with stimuli,
RecallList.reset sets the list to be used in the recall phase of the
experiment.

For more information see for...next in the e-basic help.

I hope this has been made clearer,
Tim
