I am a new SAS user working on a class project. I had each piece of this code working, but when I ran it all together to make sure it still worked, I got two errors: 'Unable to clear or re-assign the library COIMPT because it is still in use' and 'Error in the LIBNAME statement.' In results, all of the Proc Contents for Education shows twice, and all of the Proc Contents for Employment show as missing. Despite my efforts, I can't find the mistakes to fix these errors. What are my mistakes, and how can I prevent this from happening again in future steps? Here is the code:

In line 114 of the log, you call PROC CONTENTS, but you don't end it with a run; statement. So when it comes to the LIBNAME, data set COIMPT.EDUCATION is still in use by PROC CONTENTS; and so you cannot re-assign the libname while it is in use. You can fix this with

proc contents;
run;

Using the run; statement also fixes the PROC CONTENTS for Employment. The PROC CONTENTS doesn't execute until it comes to a run; but the program ends before that.

Using a run; to end all PROCs (except for SQL, GLM, REG and a few others) is a very good habit to get into.

Additional good things to get into the habit of doing: do not keep re-using the same libname to refer to multiple different data sources.

[BLT2023]

Thank you! This removed the errors from the code, and I see what I did wrong and how I can improve.

However, I am graded on the proc contents, and this did not fix what appears in results. When I run just the piece of code for 'employment':

LIBNAME Check XLSX "&CourseRoot/CDPHE Study/Data/1_Source/Employment.xlsx";
LIBNAME Check CLEAR;

LIBNAME CoImpt XLSX "&CourseRoot/CDPHE Study/Data/1_Source/Employment.xlsx";
PROC PRINT
		DATA = CoImpt.Employment;
		LABEL;
	RUN;

	PROC CONTENTS;
	RUN;

It gives me the proc contents for 'education,' and with no observations (see photo). What is the reason for this? Why would I not be seeing the two numeric values that are in the employment data? Thank you for your feedback. 

[Tom]

Your code does not make much sense at all.

You define a libref and then clear it.

LIBNAME Check XLSX "&CourseRoot/CDPHE Study/Data/1_Source/Employment.xlsx";
LIBNAME Check CLEAR;

Since SAS does not know if the meant to use CHECK to create and XLSX file or read from an existing XLSX file the first libname will work whether or not the file specified exists or not.

That might have a side effect of creating an empty XLSX file when the named file does not exist.

You then have another libref pointing at the exact same file.

LIBNAME CoImpt XLSX "&CourseRoot/CDPHE Study/Data/1_Source/Employment.xlsx";

Then a PROC PRINT step with an invalid statement in the middle of it (and a lot of random spaces).

PROC PRINT
		DATA = CoImpt.Employment;
		LABEL;
	RUN;

Perhaps you meant to include the LABEL option on the PROC PRINT statement?

You can save yourself a lot of headaches if you get in the habit of placing the semicolon that ends a multiple line statement on a new line by itself where it is more obvious when scanning the code.

PROC PRINT
  DATA = CoImpt.Employment
  LABEL
;
RUN;

Then you run a PROC CONTENTS but you don't tell PROC CONTENTS what dataset to run on. So it will run on the last dataset you created, but we cannot tell what dataset that would be since none of the code you posted created any datasets.  Perhaps you meant:

proc contents data=CoImpt.Employment;
run;

When you don't specify a data set for PROC CONTENTS, it (and all SAS PROCs) work on the most recently created data set. A LIBNAME does not create a data set. You really ought to use for PROC CONTENTS and specify the data set name.

proc contents data=CoImpt.Employment;
run;

This is another habit that you should get into and do without fail.

[BLT2023]

This makes sense, and works in my code. However, it replaces the number of observations in the results with "." How do I account for this? Thank you for answering my questions!

[Tom]

PROC CONTENTS does not know the number of observations in foreign databases.  It can only do that for actual SAS datasets. Since your code is using the foreign database engine of XLSX to point to a sheet in an Excel file then PROC CONTENTS will not display the number of observations.

If you want the number of observations you will have to either count them yourself (like select count(*) from ..... in PROC SQL code). 

Or copy the sheet to an actual SAS dataset, perhaps in the WORK library, and run PROC CONTENTS on that actual SAS dataset.

[BLT2023]

Got it, now I understand. Thank you so much for the clarification.
