Lesson 3: pg1 Library Issue

carbonec — Wed, 26 May 2021 03:21:35 GMT

Hello!

I have been working on the first demo for Lesson 3 on SAS Studio in SAS OnDemand for Academics. I started off with reloading the pg1 library file. When trying to run the print procedure for the pg1.storm_summary data set, I receive the following error message:

The code I used is (without the extra comments from the practice file):

proc print data=sashelp.cars;
	var Make Model Type MSRP MPG_City MPG_Highway;
	where Type="SUV" and MSRP <= 30000;
run;	


proc print data=pg1.storm_summary;
	*Add WHERE statement;
run;

I received the following in the log.

1 OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;
72
73 proc print data=pg1.storm_summary;
74 *Add WHERE statement;
75 run;


ERROR: An exception has been encountered.

I then re-ran the program, since the pg1 library is active. Here is the code again, with no changes:

proc print data=sashelp.cars; 
	var Make Model Type MSRP MPG_City MPG_Highway; 
	where Type="SUV" and MSRP <= 30000;

The pg1 library disappears. I then re-ran the library.sas file and the process described above follows again.

Interesting. Lots of errors related to LIBRARY but no code for how the LIBRARY is established.

I suggest that you show the LIBNAME code submitted and the LOG from that.

Typically those exceptions indicate that you either submitted some code that was so unexpected the SAS programmers couldn't provide an appropriate check/error message OR sometimes indicate a SAS installation problem. There are also odd times if you copy and paste code from some sourced, like word processor files or websites, that there are characters that you do not see in the editor that can cause all sorts of odd problems.

This bit:

80 proc print data=pg1.storm_summary;
ERROR: Libref PG1 is not assigned.
81 *Add WHERE statement;
82 run;

Means that the Library PG1 is NOT "active".

The code I used for the library is:

libname pg1 "/home/u43530149/EPG1V2/data";

The following is the log, after I run this:

 1          OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;
 72         
 73         libname pg1 "/home/u43530149/EPG1V2/data";
 NOTE: Libref PG1 was successfully assigned as follows: 
       Engine:        V9 
       Physical Name: /home/u43530149/EPG1V2/data

I messaged technical support about this issue, and they found a solution. I will post it here for future reference, if anyone else has this issue.

I had the setting Enable Accessible PDF option under Preferences > Results checked. It needs to be unchecked and the program works! Please see the included screenshot:
