Fill an array from an (unreferenced) list?

[liwenna]

Thank you for your quick reply Peter!

I will definitely try your suggestion! I never used external files to
feed info into e-prime so that's a nice thing to 'get my hands on'.

However: doesn't the use of external files influence timing?
(anyone?). And if so: would this also be the case if the whole
retrieveing of info is done in the beginning of a blockproc BEFORE the
trials start running (i.e. in my set-up combined with your/Peter's
suggestion, arrays would be filled, randomised and used to fill a
triallist BEFORE each block of trials starts running).

I think I won't have time to try it before tomorrow but I'll post back
when succesfull (and also when not actually ;) )

Thanks again!
