Fill an array from an (unreferenced) list?

[Peter Quain]

good, i hadn't run that code. there should be no timing problems 
because of the import routine - that is all going on before your 
trial procedure starts, i gather, so been and gone by the time 
important things are afoot.

Can you post how you go about populating list from array, if you have 
the time? ta
