Thanks.  I aplogize for the confusion.    In my start menu, the target for the SAS icon was: "C:\Program Files\SASHome\SASFoundation\9.4\sas.exe" -CONFIG "C:\Program Files\SASHome\SASFoundation\9.4\nls\en\sasv9.cfg"   and I added the -RLANG option in the prior config file.  I launched SAS with: "C:\Program Files\SASHome\SASFoundation\9.4\sas.exe" -CONFIG "C:\Program Files\SASHome\SASFoundation\9.4\sasv9.cfg"   And now the RLANG option is regonized:   proc options option=RLANG value; run; Option Value Information For SAS Option RLANG     Value: RLANG     Scope: SAS Session     How option value set: Config File     Config file name:             C:\Program Files\SASHome\SASFoundation\9.4\sasv9.cfg   Now I received the original error message when I try to call R:   2 3    proc iml; NOTE: Writing HTML Body file: sashtml.htm NOTE: IML Ready 4    submit / R; 5      rx <- matrix( 1:3, nrow=1)             # vector of sequence 1,2,3 6      rm <- matrix( 1:9, nrow=3, byrow=TRUE) # 3 x 3 matrix 7      rq <- rm %*% t(rx)                     # matrix multiplication 8      print(rq) 9    endsubmit; ERROR: SAS could not initialize the R language interface.  statement : SUBMIT at line 4 column 1 10   run; NOTE: Module MAIN is undefined in IML; cannot be RUN. 11   quit; NOTE: Exiting IML.

I am running the native SAS windowing environment (DMS).   Nothing has changed.  The follwoing code:   proc options option=RLANG; run;   returns NORLANG in the log.  If I try to run R from proc IML such as :   proc iml; submit / R;   rx <- matrix( 1:3, nrow=1)             # vector of sequence 1,2,3   rm <- matrix( 1:9, nrow=3, byrow=TRUE) # 3 x 3 matrix   rq <- rm %*% t(rx)                     # matrix multiplication   print(rq) endsubmit; run; quit;   I get the following error:   ERROR: The RLANG system option must be specified in the SAS        configuration file or on the SAS invocation command line to        enable the submission of R language statements. ...

Everything, SAS and R, is running on my Windows machine.   My sasv9.cfg file in SASHome\SASFoundation\9.4 directoy reads:   -RLANG -config "C:\Program Files\SASHome\SASFoundation\9.4\nls\en\sasv9.cfg"   But when I run: proc options option=RLANG;  run;   The NORLANG options is reported.   ...

Thanks.  So I understand SAS/ACCESS is not available in SAS University Edition.   I assigned the above library using a SAS 9.4 Windows 64 bit install and created datasets: * Run in SAS 9.4 Windows 64 bit ; libname testDB pcfiles path="C:\some.mdb"; libname testLIB "C:\someDirectory"; data testLIB.testDATA; set testDB.testDATA; run;   The SAS datasets now exist in C:\someDirectory .   and then I assign that directory as a library in SAS University Edition  ran a proc dataset statement to try to modify the datasets:   * In SAS University Edition; proc dataset lib=testLIB;   modify testDATA;   I got the following error: ERROR: File testLIB.testDATA cannot be updated because its encoding does not match the session encoding or the file is in a format native to another host, such as WINDOWS_64.   Why does SAS University Edition allow me to read the datasets but not modify them?  I understand I need to use SAS/ACCESS to initally connect to the MS Acess database to write the SAS datasets.  Is there a way I can create the SAS datasets in my desktop SAS 9.4 install so that I can later modify them in SAS University Edition using PROC DATASET?     ...

Thanks all.  There are now a few workable solutions. I'm using an infile specification in a datastep, so would prefer to use a date informat rather than reading in the data as a string, and then using input() to convert to a date. PG, the NLDATE informat does indeed work in the GB locale.  Thanks! ... View more

Yep, still null.  thanks for the 9.3 work around hiakuobian ... View more

I literally cut and pasted your code from above and ran it.  The data set work.test has 1 observation but myDate is null (myDate = .). The log gives no errors or warnings.  I'm running SAS 9.3 TS Level 1M2 on Windows 64 bit. ... View more

Thank you.  I tried the approach recommended by PGstats, but I get a null value.  The format/mdy(input()) combo works. ... View more
