Put Input function

ManitobaMoose — Wed, 25 Apr 2018 20:20:18 GMT

This code is generating a ton of errors. I am not sure why the input statement is not correct. The original variable ID is a character and I want to convert it to numeric, and then merge sets. The code is below. Thanks.

Libname Review'/folders/myfolders/Review' ;
Libname Learn'/folders/myfolders/Learn' ;  
Libname myformat'/folders/myfolders/sasuser.v94' ; 
Options fmtsearch=(myformat) ;
Options mergenoby=error ; 

proc sort data=learn.demographic2 ; 
	NumID = Input(ID, 3.) ;
	by NumID ;
run ; 

proc sort data=learn.survey2 ;  
	NumID = Input(ID, 3.) ;
	by NumID ; 
run ; 

Data review.Prob10_13 ; 
	merge learn.demographic2(in=indemographic2)
	      learn.survey2(in=inSurvey2) ;
	by NumID ; 
	If Indemographic2 InSurvey2 ; 
run ; 

proc print data=review.Prob10_13 noobs ; 
run ;

Start here:

proc sort data=learn.demographic2 ;
 69         NumID = Input(ID, 3.) ;
             _____

SORT sorts, it does not do any calculation. The main thing sort will expect are BY to express the order a sort occurs in or a Key statement to indicate which variable(s) might be used for a key sort.

82         If Indemographic2 InSurvey2 ;
                               _________
                               22
 ERROR 22-322: Syntax error, expecting one of the following: !, !!, &, *, **, +, -, /, <, <=, <>, =, >, ><, >=, AND, EQ, GE, GT, IN, 
               LE, LT, MAX, MIN, NE, NG, NL, NOTIN, OR, ^=, |, ||, ~=.

Then with

82         If Indemographic2 InSurvey2 ;
                               _________
                               22
 ERROR 22-322: Syntax error, expecting one of the following: !, !!, &, *, **, +, -, /, <, <=, <>, =, >, ><, >=, AND, EQ, GE, GT, IN, 
               LE, LT, MAX, MIN, NE, NG, NL, NOTIN, OR, ^=, |, ||, ~=.

IF expects some that can be compared. A single variable is evaluated to 0 for false or non-0 for true. Two variables will require some explicit comparison such as

      If Indemographic2 and InSurvey2 ;

which is true and the record kept when both variables are true (1 in this case).

notice that AND is one of the words in the "expecting one of the following" list. SAS recognized InSurvey2 as a variable and so knows something is missing.

You cannot have an assignment statement in the middle of a PROC SORT step.

Those would need to be in a DATA step.

Re: Put Input function

Astounding — Wed, 25 Apr 2018 20:38:48 GMT

PROC SORT doesn't let you create new variables. It only sorts the existing data.

If you want to create NUM_ID, you need a DATA step to do that. Then run PROC SORT next.

For your later error regarding the IN= variables, please explain what you want that section to accomplish.

OK, looks like it's a little crowded here. Time for me to go home!

Re: Put Input function

ManitobaMoose — Wed, 25 Apr 2018 21:21:38 GMT

Ok, for the IN= I just forgot the AND. That is no problem.

The bigger issue I am having is with renaming the vars. Below does not seem to work, and the variable NumID is not recognized.

Libname Review'/folders/myfolders/Review' ;
Libname Learn'/folders/myfolders/Learn' ;  
Libname myformat'/folders/myfolders/sasuser.v94' ; 
Options fmtsearch=(myformat) ;
Options mergenoby=error ; 

Data review.rename_vars ; 
	Set learn.demographic2 ; 
	NumID = Input(ID, 3.) ; 
	Set learn.survey2 ; 
	NumID = Input(ID, 3.) ;
run ; 
	
	
proc sort data=learn.demographic2 ; 
	by NumID ;
run ;

proc sort data=learn.survey2 ; 
	by NumID ;

Re: Put Input function

You must Must MUST learn the meaning of basic statements. Take this DATA step:

Data review.rename_vars ; 
	Set learn.demographic2 ; 
	NumID = Input(ID, 3.) ; 
	Set learn.survey2 ; 
	NumID = Input(ID, 3.) ;
run ;

The DATA statement names the data set being created. The SET statement names the data set being read in. (At a more advanced level, there's definitely more to it, but let's take the basics here.)

All the subsequent changes made by your programming statements (such as creating NumID) have zero impact on the contents of learn.demographics2. All the changes are part of the data set being created, review.rename_vars. So when your later steps use learn.demographics2, those steps are using a data set that does not contain NumID.

Now I'm not sure what your plan was, and why you are using two SET statements. But this DATA step definitely changed the contents of review.rename_vars. You may need to rebuild it.
