Count the keywords of the string

[Abud]

Hello everbody!

Can I count the keywords of the string ?

Example :

%let colors = blue green yellow; ( I'd like to know if there is a function to return the number 3);

tk's in advanced !!

Yes there is a function for that.

My question is why do you want to know?  Does it really matter?  Can you do what you want with the list of words without knowing how many there are?  I bet you can.

example:

data have;

string=' blue green yellow';

n=countw(string);

proc print;run;

%let n=%sysfunc(countw(&colors));

%put &n;
