HI RW9, Thanks for the suggestion. The reason I prefer Proc import is that it's simpler, whereas input would need to type into the variable names and I have a lot of variables in the file. Also, I have trouble to define the formats of the variables. see the following values as example, what's the correct format? 1.17E+00 -1.22E-01 I tried e8. and e9., but each only recognize certain columns but not others. Thanks, York
