Unable to access library file

[ketone]

New to Sas and trying to complete online training.

The e-learning shows the steps to create a library called PG1, PG1 successfully created:

1 OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;

70

71 libname PG1 "/home/u12345678/EPG194/data";

NOTE: Libref PG1 was successfully assigned as follows:

Engine: V9

Physical Name: /home/u12345678/EPG194/data

72

73 OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;

84

Trying to access the files using proc print data= "PG1/np_summary" (np_summary is in PG1 folder), the error below returns:

1 OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;

70

71 proc print data="pg1.np_summary" (obs=20);

ERROR: Extension for physical file name "pg1.np_summary" does not correspond to a valid member type.

73 run;

Thanks!

Hi:
You should NOT have quotes after data= option. It should just be:
proc print data=pg1.np_summary (obs=20);
... more code...
run;

When you use a 2 level SAS name, you do NOT need quotes. The LIBNAME statement already points to the operating system folder path for the data. So, SAS knows to look for the np_summary.sas7bdat file in that location when you use the 2 level name. If you remember, back in the early part of class, we had you use the fully qualified path for the storm_summary data, like this:

proc contents data="/home/<yourUserID>/EPG194/data/storm_summary.sas7bdat" ;
run;

With a LIBNAME statement defined,

libname pg1 '/home/<yourUserID>/EPG194/data';

you can use the "nickname" or libref of PG1 to tell SAS where the SAS data is located in a folder on the operating system. SAS knows that SAS tables have a file extension of sas7bdat, so you can simplify the DATA= option with an UNQUOTED 2 level name, as shown below:
proc contents data=pg1.storm_summary ;
run;

OR

proc contents data=pg1.np_summary ;
run;

OR

proc print data=pg1.np_summary ;
run;

Hope this helps,
Cynthia

It works! Thank you Cynthia.
