SAS programming 1 lesson 2 activity 2

JaxonKing — Sat, 23 May 2020 14:00:37 GMT

I am having a slight issue when trying to do the proc contents data activity. When putting the code in with my file it is coming up with the error the physical name is too long (5 folders deep in Z drive to get to EPG1V2). Even after shortening it to a couple of folders higher than EPG1V2 it still gives the same message, am I missing something with my formatting?

proc contents data="Z:\Users\UKGC\Documents\Coding\SAS\EPG1V2\data\storm_summary.sas7bdat";
run;

The above is the code I am using.

Assign a libname first:

libname test "Z:\Users\UKGC\Documents\Coding\SAS\EPG1V2\data";

then use the library to address your dataset:

proc contents data=test.storm_summary;
run;

Use any valid SAS name with a maximum length of 8 in place of "test".

Thank you for your reply, unfortunately, the solution didn't work, it comes up with a different error and creating libraries was the next section of the course so hopefully, I can figure out the new issue there.

I am trying to find out what the issue was with the physical file name length and which bit I need to change to hard code the pathway as in the course, can't understand the error as the storm_summary.sas7bdat is used in the example in the course.

Please post the logs of your initial try with the physical name, and that of the libname assignment.

sorry if I have missed something basic but I just can't figure out what has gone wrong.

Re: SAS programming 1 lesson 2 activity 2

Kurt_Bremser — Sat, 23 May 2020 16:12:43 GMT

This is your clue:

NOTE: Library CODING does not exist.

SAS cannot "see" the path you specified. There are lots of possible reasons for this:

your SAS server uses a UNIX system and needs different pathname syntax
the (obvious) shared network resource is not available on the server
there is a subtle mistake in the spelling of the path

just to name a few

JaxonKing — Sat, 23 May 2020 16:32:18 GMT

Thank you,

As I was working on the files and data sets from the course download the file directory that I called from was different from where some of it is saved. I changed the file pathway and it is now working for both the initial and the library function.

Had to right-click properties on the storm_summary to find out it was different.

Thank you for your help and time.

Hi:
Just a note. There are 2 PROC CONTENTS activities using the storm_summary data. In the first activity, we want you to use a fully qualified path name so that you see it IS possible to use an operating system specific path name for the data= option.

For example, on my SAS University Edition folder, the fully qualified path for the storm_summary file is:
/folders/myfolders/EPG1V2/data/storm_summary.sas7bdat

On SAS OnDemand for Academics, the fully qualified path for storm_summary is:
/home/<userID>/EPG1V2/data/storm_summary.sas7bdat

On SAS for Windows local install, the fully qualified path is:
c:\SAS_class\EPG1V2\data\storm_summary.sas7bdat

So, the first PROC CONTENTS activity has you do this:
proc contents data="/folders/myfolders/EPG1V2/data/storm_summary.sas7bdat";
run;
or
proc contents data="/home/<userID>/EPG1V2/data/storm_summary.sas7bdat";
run;
or
proc contents data="c:\SAS_class\EPG1V2\data\storm_summary.sas7bdat";
run;

After we show students that they CAN use an operating system path name, next we show students the LIBNAME method as explained by @Kurt_Bremser. With a proper LIBNAME statement such as:
libname pg1 "/folders/myfolders/EPG1V2/data";
libname pg1 "/home/<userID>/EPG1V2/data";
libname pg1 "c:\SAS_class\EPG1V2\data";

Then the PROC CONTENTS code would be the same:
proc contents data=pg1.storm_summary;
run;

Hope this clarifies what we were intending in the course. If you're using SAS Studio, it is always possible to find the correct path for the LIBNAME statement by doing a right-mouse-click on the data subfolder under EPG1V2 and then choosing Properties. The Location field in the Properties window will show you the correct path to use for your LIBNAME statement.

Or, you can right-click on the data table file (the sas7bdat file) and choose Properties if you prefer to use the full operating system path method.

Please read and follow the instructions for your environment. SAS on Demand runs on UNIX servers in the cloud and does NOT have access to your C: drive.

thank you so much for pointing this out! it works this time!!

Hi: Please do not bury your post inside another posting. I almost didn't see it. How are you using SAS:
1) local copy of SAS on windows (click the SAS icon from the Start Menu)
2) SAS University Edition in a Virtual Machine (start SAS Studio by first opening Virtual Box or VMWare Player to start)
3) SAS OnDemand for Academics (start SAS Studio by clicking in SAS Control Center Dashboard)
4) Using SAS Enterprise Guide

The instructions you follow will determine how you should write your code. Are you using SAS Studio? If you right click on the storm_summary.sas7bdat file and choose Properties, what is the full path you see in the Location field in the Properties window -- this is what you should have in your code.

Post a screen shot of your Properties field and then post the log that shows an error message on that same path....that EXACT same path.

This is for the web-based SAS Studio version. Right click the (virtual) folder where the file is and click "properties." It will show you the path. Mine is /home/u167737/EPG1V2/data. So the correct programming line would be

proc contents data="/home/u167737/storm_summary.sas7bdat"; run;

Good luck!

Hi:
Actually, you have to account for the full path in the data= option when you use the full filename and extension. When we create the data for the course, we put the storm_summary.sas7bdat file in the EPG1V2/data folder. So in this case, the correct path would be:
proc contents data='/home/<youruserID>/EPG1V2/data/storm_summary.sas7bdat';
run;
All absolute file paths on the On-Demand server must start with /home/<youruserID>/ (everybody has a different userID. Then the class folder (if you followed the instructions) of EGP1V2/ and the subfolder of data/. Finally the file name and file extension, storm_summary.sas7bdat. Later in the class, we'll show you how to use a LIBNAME statement to bypass the need to use the fully qualified path like this.
We always recommend the right-click and Properties method to see the full path.
