How to use the PROPCASE function

Using the PROPCASE function

The "old" way to capitalize the first letter of words was to use LOWCASE, UPCASE, and the SUBSTR function, like this:

DATA CAPITALIZE;
INFORMAT FIRST LAST $30.;
INPUT FIRST LAST;
FIRST = LOWCASE(FIRST);
LAST = LOWCASE(LAST);

SUBSTR(FIRST,1,1) = UPCASE(SUBSTR(FIRST,1,1));
SUBSTR(LAST,1,1) = UPCASE(SUBSTR(LAST,1,1));

PROC PRINT DATA=CAPITALIZE NOOBS;
TITLE "Listing of Data Set CAPITALIZE";
RUN;

With the PROPCASE function in SAS 9.1, it's much easier.

DATA PROPER;
INPUT NAME $60.;
NAME = PROPCASE(NAME);

PROC PRINT DATA=PROPER NOOBS;

RUN;

Example:

data test;
x=lowcase('MY NaMe iS SARaTh');
y=propcase(x);
z=propcase(lowcase('I AM A PROGRAMMER'));
a=lowcase(z);
b=upcase(x);
run;
