This is how I read files and it works allright. Doing In[1]:= ReadList["flnm",RecordLists->True,Numbers] should return the list flnm and print it below. Sometimes I assign the name before, as in In[2]:= data=ReadList["flnm",RecordLists->True,Numbers] but I may also assign the names afterwards, as in In[3]:= ReadList["flnm",RecordLists->True,Numbers] ; In[4]:= data = %; Check first if your file "flnm" is not empty, using In[5]:= !! flnm Good luck, Tomas Garza Mexico City
