Dynamically changing Column Name based on other fields

[S_Nav]

I have a data set that I need to reorganize into columns and I'm worried there will be too much risk for human error if I try to hard code them all.  Data set example:

ID	QUESTN_CD	QUESTN_TXT	QUESTN_ANSWER_TXT
123	1	Gender	M
123	2	Age	36
123	3	Fulltime	Y
123	4	Hourly Pay	N

My desired output is something like this:

ID	GENDER	AGE	FULLTIME	HOURLY PAY
123	M	36	Y	N

Code example with dummy data:

PROC SQL;
   CREATE TABLE QUESTNS AS 
   SELECT DISTINCT t1.*,
          t2.QUESTN_ANSWR_TXT AS 'Contract Signed'n, 
          t3.QUESTN_ANSWR_TXT AS 'Assignment Start Date'n,
	  t4.QUESTN_ANSWR_TXT AS 'Correct W4'n, 
          t5.QUESTN_ANSWR_TXT AS 'Name Spelled Properly'n, 
          t6.QUESTN_ANSWR_TXT AS 'Alterations to Assignment'n,
	  t7.QUESTN_ANSWR_TXT AS 'Assignment Type'n
      FROM WORK. PERSON_INFO t1 
			left join QUESTN t2 on t1.ID = t2.REF_ID
			left join QUESTN t3 on t1.ID = t3.REF_ID
			left join QUESTN t4 on t1.ID = t4.REF_ID
			left join QUESTN t5 on t1.ID = t5.REF_ID
			left join QUESTN t6 on t1.ID = t6.REF_ID
			left join QUESTN t7 on t1.ID = t7.REF_ID
      WHERE (t2.QUESTN_CD = 9 AND t3.QUESTN_CD = 23 AND t4.QUESTN_CD = 8 AND t5.QUESTN_CD = 29 
		AND t6.QUESTN_CD = 37 AND t7.QUESTN_CD = 22);
QUIT;

But I think there's too much room for human error in manually renaming each column based on the question code, given that there are over 40 question codes (for now) and the data source may update and change without my knowledge.

Any and all advice appreciated!

Look up PROC TRANSPOSE instead.
