In Program 9.6, the NEW_NAME variable is created by changing the

NAME variable to its proper case by using the PROPCASE function. NEW_

COMMENTS is generated by changing each value for COMMENTS to

uppercase with the UPCASE function.

Program 9.6:

data ex9_6;

set ch9.tenant;

new_name = propcase(name);

new_comments = upcase(comments);

run;

title 'Illustrating the use of PROPCASE and UPCASE functions';

proc print data = ex9_6 (obs = 5);

var name new_name comments new_comments;

run;

Output from Program 9.6:
