Whats wrong with this code ?

SAS is giving me this error :- NOTE: Line generated by the invoked macro "ICODES".
129 select distinct enrolid, dx&i. as code from derived._01_itable

You are comparing the letter i to the digits 14

i < 14

Instead of testing the value of the macro variable i

&i < 14

Even if you get this to work, it seems extremely inefficient to read your data set 14 times just to be able to transpose the data.  Why not just use PROC TRANSPOSE?

how to do that ? I'd like to see how to do it both by my code (macros) and proc transpose

Hint:

 

Use 

 

options mprint;

before calling the macro, then the error message will be much easier to debug.

 

Hint 2:

 

When including a SASLOG into this forum, use the {i} icon that will space the letters properly so we can see exactly what is underlined.

Just use PROC transpose

proc transpose data=derived._01_itable 
  out= _01_itable2 (rename=(col1=code)) 
;
 by enrolid ;
  var dx1-dx14 ;
run;

Although if you really do have multiple records per ENROLID you might need to first decide which one you want to transpose.

Or create a new variable that will uniquely id the rows that you can use in the BY statement for PROC TRANSPOSE and then add a PROC SORT NODUPKEY to remove the multiple copies of the same ENROLID, CODE combinations.
