What if the %LET = a column name, but it doesn't define a specific row of dat? What value does it receive?
I'm not a SAS programmer, just trying to read it and convert it to SQL. The routine creates a table of values and does this:
PROC SORT DATA=CURNSN&cnt; BY IINSGM; RUN;
%LET newcol&cnt=IAC_&Q._&NUDCYCLE;
%LET nicd&cnt=NEWITMCD_&Q._&NUDCYCLE;
I have the &cnt value, the &Q value and the &NUDCYCLE value. Both LET values correspond to a column. Which row will provide the value? I'm guessing the last, or possibly the first?

It's not clear what you are trying to do. Please explain further what you are trying to do.

 

Macro variables are just text strings. In the first statement, if suppose &CNT = 2, for example, you are creating a macro variable named NEWCOL2 which has some value ... the value depends on the value of &Q and &NUDCYCLE, but it is a text string, and this macro variable value is unrelated to any particular data set or value within a data set. The value of &NEWCOL2 is simply a text string, outside of a data set.

Hi @Florent 

The discussion forum SAS Macro Facility, Data Step and SAS Language Elements sounds interesting, but I haven't been able to find it anywhere in communities.sas.com. May I ask for directions to get there?

 

thanks
