Thanks for all your helps.

I am using Mathematica 4.0. It might not support Import function, 
since the expression you proposed to me cannot work. 

In[2]:=
Import["data.csv"]

Import::guess: Could not guess format from channel data.csv.

Out[2]=
Import["data.csv"]

In[3]:=
Import["data.csv", "CSV"]

Import::format: "CSV" is not a recognized Import format.

Out[3]=
Import["data.csv", "CSV"]

Fortunately, Sseziwa's method works fine to me.

{ToExpression[#[[1]]],#[[2]],Sequence@@Table[ToExpression[#[[i]]],{i,3,8 
}]}&/ 
@ReadList[strm,Word,WordSeparators\[Rule]{","},RecordLists\[Rule]True]
