I know that the finfo function in SAS returns filesize as one of the info fields in Unix. Is there an equivalent in Windows?
I need to be able to get the total disk space used in a particular folder from within SAS/AF code. Any suggestions would be welcome.
Thanks,

i've previously posted a sas macro to read windows directory listing here.
If you have SAS version 9.2 or later then this link will work regardless of OS:
http://support.sas.com/kb/38/267.html
Here is a paraphrased version of the link answering your question exactly:
%let filename = d:\sasdev\autoexec.sas;
data info;
length filesize $60;
drop rc fid close;
rc=filename("myfile","&filename");
fid=fopen("myfile");
filesize=finfo(fid,"File Size (bytes)");
close=fclose(fid);
put filesize=;
run;
Cheers

PS - Have you checked out www.runsubmit.com? It's just like StackOverflow but for SAS related questions only.
I'm going to do something crufty and write a utility function that does the following:
If the file is a SAS dataset, then use standard SAS functions to get the filesize (some lrecl and nobs math)
Otherwise, if it is UNIX or SAS 9.2, use finfo
Otherwise, use a modified version of the macro written by #rkoopmann
Note that this is ok for me only because my requirements are to be able to get the size of a particular file.

I am attempting to format variables in SAS studio which have been truncated due to the name being longer than 32 characters, when I attempt to format the variables in SAS studio it gives the warning 'this variable in uninitialized'. when I run the same code in SAS EG against the same excel document imported, the code works fine and formats the variable. Why would the same code in SAS studio not work?
code:
data test;
set test1;
format 'variable'n best12.;
run;
Compare the value of option VALIDVARNAME in EG vs Studio. Set it in studio to the same as EG.
Two common ways to view the current setting of an option. Proc OPTIONS or function GetOption
proc options option=validvarname;
run;
%put %sysfunc(getoption(validvarname));
The code won’t be the same because you’re using two different applications with different default settings most likely. As someone else indicated, it’s likely the validvarname option that’s the issue. I would recommend setting it to V7 which avoids these issues. With this setting, SAS converts them to valid variable names by default and you can avoid the rename step entirely.
Supposedly the 32 char limit will be lifted in SAS 9.5. No release date has been announced, SAS 9.4 M5 was recently released so I’m not expecting it super soon.
I've scoured the internet but cannot seem to figure this out. My question is, if I have a sas7bdat file, how can I read a sas7bdat file in SAS studio so that I can work with it.
I've tried:
libname test 'C:\Users\name\Downloads\test.sas7bdat';
which gives me the error that library test does not exist and if I try the following, I know that I need an INPUT which I don't know of unless I can see into the file.
DATA test;
INFILE 'C:\Users\lees162\Downloads\test.sas7bdat';
RUN;
Is there something I'm missing?
Libref's that you create via the LIBNAME statement point to directories, not individual files.
libname test 'C:\Users\name\Downloads\';
INFILE is for reading raw data files. To reference an existing SAS dataset you use a SET statement (or MERGE,MODIFY,UPDATE statement).
set test.test ;
Note that you can skip defining a libref and just use the quoted physical name in the SET statement.
DATA test;
set 'C:\Users\lees162\Downloads\test.sas7bdat';
RUN;
Of course to use C:\ in the paths this is assuming that you are using SAS/Studio to point to full SAS running on your PC. If you are using SAS University Edition then it is running in a virtual machine and you will need to put the SAS dataset into a folder that is mapped to the virtual machine and then reference it in the SAS code with the name that the virtual machine uses for the directory.
So something like:
DATA test;
set '/folders/myfolders/test.sas7bdat';
RUN;
Libname is just pointing the location and once you have done that you can use that libname followed period and dataset in your set statement
libname test "C:\Users\name\Downloads";
DATA test;
set test.asl;
RUN;
One possible reason could be that you are using the SAS University edition (It doesn't support variable library address).
From one of the SAS community Q/A:
"When you are using the SAS University Edition, any libraries that you create must be assigned to a shared folder. You access your shared folder with this pathname: /folders/myfolders/. Always use '/' in the directory path, even in Windows operating environments"
After setting the directory address, proceed as instructed by Tom above in one of the answers.
Suppose you have the sas dataset at location. C:\Users\name\Downloads\test.sas7bdat
libname download 'C:\Users\name\Downloads';
proc sql;
select * from downloads.test;
run;
you can read your dataset like a table using the proc sql, in case you want to query the dataset, but if you want to modify the existing dataset then you can use the data setp as mentioned by #krian.
I'm trying to move a SAS dataset over to our Linux server from a client. They created it on SAS 9.4, 64-bit on Windows 7. I'm using SAS 9.4, 64-bit on Linux.
If I do
proc datasets library=din;
run;
I get the following in my log
Libref DIN
Engine V9
Physical Name /sasUsr/DM/DATA/SAS_DATA/201510_SSI
Filename /sasUsr/DM/DATA/SAS_DATA/201510_SSI
Inode Number 46358529
Access Permission rwxrwxr-x
Owner Name cvandenb

1 SAMPLE_FROM_SSI DATA 131072 09/14/2015 17:07:01
2 TEST DATA 131072 09/15/2015 09:35:59
15 run;
but when I do
data test;
set din.sample_from_SSI;
run;
I get
18 data test;
19 set din.sample_from_SSI;
ERROR: File DIN.SAMPLE_FROM_SSI.DATA does not exist.
20 run;
I also created a dummy dataset din.test and was able to proc print it. This seems to either be a version compatibility issue or transmission issue. I thought this would be straightforward. Any suggestions? I'm moving the file from windows to Linux with WinSCP. I'd rather not have to request a .csv and create the input statement, but will if I have to. Your help is appreciated.
Thanks,
Cory
If you are talking about an actual SAS dataset then make sure that the name of the file is in all lowercase letters and has the extension of .sas7bdat. If the source file from Windows did not have an extension of .sas7bdat then perhaps you are not dealing with a SAS dataset, but some other type of file.
In SAS code it does not matter whether you reference a dataset using upper or lower case letters. So you can reference a datasets as sample_from_SSI or Sample_From_Ssi to refer to the same file. The same is true of general filenames on a Windows machine. But on Unix system file names with different use of upper and lower case letters are distinct files. SAS requires that the filename of a SAS dataset must be in all lowercase letters.
So if you write:
libname DIN '/sasUsr/DM/DATA/SAS_DATA/201510_SSI';
proc print data=DIN.SAMPLE_FROM_SSI;
run;
Then you are looking to make a listing of the data in a file named:
/sasUsr/DM/DATA/SAS_DATA/201510_SSI/sample_from_ssi.sas7bdat
I usually get a note about CEDA in this case not missing data.
Create either a CPORT or XPORT file using the associated proc, PROC CPORT or XPORT and then move that file.
Try referring to the data with all caps as well, which I don't think should be the issue, but is possible.
I would try using PROC COPY directly on the libname, as you can select memtype=data that way without explicitly specifying the file.
If SAS still can't do that, then you might have a permissions issue or something else that is outside of the SAS realm I suspect.
Try using PROC CPORT and PROC CIMPORT.
Use the CPORT Procedure to convert the file into a transport file.
Use the CIMPORT Procedure to convert the transport file to a SAS format.
There is an example that sounds similar to what you are doing here.
According to SAS, the general procedure is:
A transport file is created at the source computer using PROC CPORT.
The transport file is transferred from the source computer to the target computer via communications software or a magnetic medium
The transport file is read at the target computer using PROC CIMPORT.
Note: Transport files that are created using PROC CPORT are not
interchangeable with transport files that are created using the XPORT
engine.
If that doesn't work, or it is taking a very long time to figure out, it would be faster to ask them for a CSV and import it directly using PROC IMPORT. It should read in quite easily, especially if it comes from PROC EXPORT.
Hopefully someone out there will have run into this before. I'm trying to use the street level geocoding capability of SAS' PROC GEOCODE, but I keep getting a cryptic error. I couldn't find anything on the net about it (although to be fair I only spent a half hour looking).
First, I'm using SAS Enterprise Guide (I've tried on both v4.2 and v4.3), although I still prefer to program as I find the point and click interface quite limiting. Maybe this right here is my problem?
Anyway I first get the lookup data sets from http://support.sas.com/rnd/datavisualization/mapsonline/html/geocode.html and follow the instructions in the readme. I also use the pre-written SAS program to import the CSV files. My input dataset contains just 4 variables: street address, city, state, and zip. I then run the following code:
libname josh 'C:\Users\Josh\Desktop\Geocode\SAS files';
proc geocode
method=street
data=SASUSER.Home_Policy_Address_Detail
lookupstreet=josh.USM
out=test;
run;
However I get this error:
ERROR: Variable NAMENC not found in JOSH.USM data set.
Nowhere in the readme or the import program is a variable named "NAMENC" ever mentioned. This is what has me stumped. Is it something wrong with the simple PROC GEOCODE program I wrote? Is it due to me using SAS EG (although I've yet to run into a base SAS procedure that hasn't worked on EG)? Or something else?
Any help/guidance would be much appreciated. Thanks in advance!
Check your SAS version. You can use the 'Help' menu in DMS mode or submit this statement:
%put &sysvlong;
It looks like you are using SAS 9.3 but your lookup data JOSH.USM is the lookup data formatted for SAS 9.4.
PROC GEOCODE street lookup data comes in two slightly different formats, one for SAS 9.3 and another for 9.4. When you download the nationwide lookup data from the SAS MapsOnline geocoding page, make sure to download the version appropriate for your SAS release.
I have data inside SAS.
I want to store the datafile to SPSS format (*.sav)
I use the following program:
PROC export Data=SASdataToStoreInSPSS
FILE="Path\Filename_%sysfunc(today(),date9.).sav"
dbms=sav replace;
RUN;
This works great. Except when I open the file in SPSS the dates are strangly formatted.
For example:
156405 08:51:00
Should be
3-Jan-2011 08:51
I can manually change the data formats in SPSS. So the values are correct date values, except they are not automatically formatted in a readable format.
I tried to change the format in SAS before saving to DATETIME20. or DATETIME23.3. But this does not help.
I want this to work without having to open SPSS and run a Syntax there.
The SPSS files that SAS spits out have to be directly mailed to other users of the data.
I think this is either a bug with SAS's export, or an issue with SPSS where some default changed. What's happening is that SAS is storing it as a SPSS Date - but with width 16, which is not long enough to hold the complete datetime. I don't think you can use DBDSOPTS with DBMS=SPSS, so I don't know that there is a good workaround short of importing the file into SPSS.
You could do that automatically, though, using the SPSS Production facility; I've written an import script before and asked SAS to run spssprod with the batch file. That's an irritating workaround, but it might be the easiest, unless SAS Tech Support can help you (and certainly try that - they are usually only a few hours' turnaround for initial contact at least).
SAS mentioned it has to do with the SPSS driver they use. Apparently it is not an easy fix so they forwarded the issue to second-line tech support.
The workaround you will need is split the dates in two columns. One with date and one with time.
data SPSS2;
set SPSS;
date = put(datepart(DatumSPSS), date9.);
time = put(timepart(DatumSPSS), time8.);
run;
Or you can tell the end user how to change the format of the date in SPSS.
For an automated approach, try this .NET app. You need SPSS, but SAS is not required to convert a large collection of SAS files automatically.
