Hi Bob,

You can try the following.

(* I interpreted your list as numbers separated by both ','
and ';'. *)
data=ReadList[<enterfilename>,Word,WordSeparators->{",",";"}];

(* Note - I didn't test this code - you might have to
convert the above from a list of strings to a list of
numbers by using the ToExpression command before going to
the next step since you can't do computations with strings.
But if your list contains numbers in fortran notation then
you can use StringToStream[] which is a little but tricky to
deal with. *)

data2=Partition[data,3];
Map[{#[[1]],#[[2]]*10+#[[3]]}&,data2]

Hope this helps,
Lawrence
