Convert from char to Num a list of variables

Question

I use the following code to add empty columns to my data set. How can I specify that they must be numeric instead of character?

Thank you in advance

       data mydb;
         set all;
           array c{54} $100;
       run;

I would like columns from c1 to c54 to be numeric. By default they are char. Thank you in advance

Answer 1

No. By default they are numeric. You set them to character with a length of 100 with the $100 part of your Array Statement.

Simply do this to make them numeric.

data mydb;
   set all;
   array c{54};
run;
