Dear MathGroup members
I have to do replacements in very long lists. An efficient way to do
this is to use
x[[index]]=newElement.
This, however, doesn't work if I want to do replacements for a set of
lists. If I try to replace the third element in the lists v1, v2 and v3 by
typing
Scan[#[[3]] = newElement &, {v1,v2,v3}]
I get the error message
Set::setps: #1 in assignment of part is not a symbol.
Any suggestions?
Thanks
