Once again, if you use EP2.0.10 or later, I think you can do this better with Task Events than with inline code. How about the following:<br>
<br>
Suppose you use the object StimSlide to get your subject response. Make sure that it logs StimSlide.ACC; you might also have to set its PreRelease to 0 to make sure that E-Prime sets the StimSlide.ACC attribute before executing the next object. Set up your trial Procedure something like<br>
<br>
...<br>
StimSlide<br>
MarkerWait<br>
...<br>
<br>
MarkerWait is a Wait object with a Duration of 0. Add a Task Event at StartTime, ActionTime, or OnsetTime (in this case it hardly matters which, if you want to know the difference please see <a href="https://groups.google.com/d/topic/e-prime/OeiZ00V9SRc" target="_blank">https://groups.google.com/d/<u></u>topic/e-prime/OeiZ00V9SRc</a> ). Set it to use your communications device (ParallelPort, Serial, etc.). Use WriteString as the Action, "(custom)" as the Source, "[StimSlide.ACC]" for Custom, String for Data Type; leave Delay at 0, and Enabled at Yes.<br>
<br>
The key is the Custom value for the Task Event. If StimSlide is set to log .ACC, then E-Prime will automatically create the StimSlide.ACC attribute (though you might have to set PreRelease to 0 to make sure that MarkerWait does not try to use that attribute before its value is set!). Then MarkerWait can use that as an attribute reference in the Custom value.<br>
<br>
I have not tested this out myself, so I will be very interested to learn what you get to work. Please write back.<br>

Hello I need help with sending an alphanumeric marker when presenting a stimulus. I have set the port for communication and already have successfully sent markers to another program.Â<br>
<br>
My wish now is to send markers if stimuli are correct or incorrect. So for example if stimulus is correct send marker "1" and if stimulus is incorrect send marker "0". I need to understand how  in-line script does this and what to write in the in-line script for it to perform the function specified.<span class=""><br>
<br>
Thank you in advance!!!<br>
<br>
Juan<br>
