ERROR: File WORK.YEAR.DATA does not exist

[ManitobaMoose]

Hi,

I cannot figure out why this is being generated. Everything looks ok to me.

------------------------------------

First, here is the learn.errors file:

libname Learn '/folders/myfolders/Learn' ;

data learn.errors;
   input Subj : $3.
         PartNumber $8.
         Name & $20.;
datalines;
001 L1232 Nichole Brown
0a2 L887X Fred Beans
003 12321 Alfred 2 Nice
004 abcde Mary Bumpers
X89 8888S Gill Sandford
;

Second, here is the code that is giving me a 'file mixed_data.data does not exist' error:

libname Learn '/folders/myfolders/Learn' ;

Data Check1 ;
    Set Learn.Errors ;
    If anyalpha(Subj) then output mixed_data ;
    else output only_nums ;
run ;

proc print data=mixed_data noobs ;
run ;;

--------------------

In my understanding, the anyalpha(subj) should produce a file with the datalines from the learn.errors set in which the Subj has letters in it. Why is this creating this error?

Thanks!

Output data sets need to be named on the DATA statement. 

Data mixed_data only_nums;
