[deleted_user]

Hello,

I'm gettina errror in log .I used the code -

libname sc 'c:\Sas\sales';
data test;
proc reg;
model Score = Processor Memory Disk Video Battery/ collin;
proc print data = test;
Run;

log -

ERROR: Variable SCORE not found.
ERROR: Variable PROCESSOR not found.
ERROR: Variable MEMORY not found.
ERROR: Variable DISK not found.
ERROR: Variable VIDEO not found.
ERROR: Variable BATTERY not found.
NOTE: The previous statement has been deleted.

I had an excel file which i converted it to "laptop_review.sas" and then to "sales.sas7bdat".If I'm wrong somewhere please suggest me how to correct it as I've been trying for long to run the code.

For some reason, you have decided to omit the key part of your SAS log - that is the DATA step logic used to read up your external data file. If you expect others to provide you feedback and guidance, you must share the entire SAS log by pasting the content in your forum post reply - not just the portion of the SAS program that is convenient or what you might believe is all that is relevant.

Also, your INFILE statement is referring to a SAS data file, not an external file. You would normally have a LIBNAME pointing to the file directory/folder and use a SET statement to input SAS data files -- not using an INFILE statement since this is not an external file.

And, do consider that you may have already started a related post here - http://support.sas.com/forums/thread.jspa?threadID=8824&tstart=0

If you review the SAS-generated log and the input record dump, it may be revealing...mostly because your INFILE statement is pointing (I believe) to your SAS program and not your input data. I have to wonder just how much time you are willing to invest to learn the SAS system and its programming facilities?

Suggest you start with analyzing your SAS DATA step and get your input data properly read up into a SAS file - then begin to consider using PROCs to analyze the data.
