Recover file in PG1 library

[JohnWeyk]

*How do I recover a file?

I am learning SAS using University SAS Studio and I came across the following problem. The eu_occ table that is part of the PG1 library of the Essentials 1 course is only showing the Country and Geo columns:

*Run pg1.eu_occ;
data pg1.eu_occ2;
	set pg1.eu_occ;
run;

Using statements suggested by Roger Dean:

*Statements by Roger Dean;
data WORK.EU_OCC;
   infile datalines dsd truncover;
   input Geo:$2. Country:$40.;
   label Geo="Country Code" Country="Reporting Country";
 datalines;
 AT Austria
 AT Austria
 AT Austria
 AT Austria
 AT Austria
 ;;;;

 NOTE: There were 5 observations read from the data set PG1.EU_OCC.
 NOTE: DATA statement used (Total process time):
       real time           0.00 seconds
       cpu time            0.00 seconds
       
 
 250        
 251        OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;
 263        

How can I recover the original file? It is necessary for other stages of the course.
I have tried to create a new library, called PG2 but it just makes a copy of PG1.

Any suggestions?

Go back to the original setup code and run it again - but consider putting it in a different folder. Then replace the one file you want.

If you're on Windows you can try the Previous Versions trick via File Properties in Windows Explorer if you have it turned on.

Thank you very much, I managed to recover the original file using Windows.

Hi @JohnWeyk 

In addition to @Reeza 's answer, you can put access=readonly in the libname statement to avoid this kind of issue.

libname pg1 "&path./data" access=readonly;

Thanks for the tip.

I think the course requires you to write to that library periodically though?
