How to Change Variable name

[Kalai2008]

Hello,

I need a help changing the Variable name from upper case to Lower case, but not the values in that column. I have more than 200 columns and one of them needs to be in lower case instead of upper case. Example ( TOTAL_COUNT  to total_count) I only have the dataset available. 

Thanks for looking.

Have you tried:

data want;

retain total_count;

set have;

run;
