I have bw1-bw1000 and i want to make a new version of each that is divided by 12
Made a data step and put this array, but it is not working:
do i=1 to 1000;
You didn't include the whole data step so it is hard to tell.
data want ;
set have ;
array newbw (1000) ;
array bw (1000) ;
do i=1 to 1000;
newbw[i]=bw[i]/12;
end;
run;
The code above assumes that you have 1,000 numeric variables named BW1 to BW1000 and you want to create 1000 new variables named NEWBW1 to NEWBW1000.
You didn't include the whole data step so it is hard to tell.
data want ;
set have ;
array newbw (1000) ;
array bw (1000) ;
do i=1 to 1000;
newbw[i]=bw[i]/12;
end;
run;
The code above assumes that you have 1,000 numeric variables named BW1 to BW1000 and you want to create 1000 new variables named NEWBW1 to NEWBW1000.
OK thanks, was not aware I had to define both bw and newbw
You need to get into the habit of reading the log.
Your code would have generated something like:
ERROR: Undeclared array referenced: newbw.
ERROR: Variable newbw has not been declared as an array.
Telling you exactly what the issue was.
