counting symbols in a string

[Ken_oy]

how to count ", " in a string?

for example:
any function can return a number "2" when counting in the following string?

" one, two , three"= two commas.

Thanks a lot!

have you tried the count() function?

[Ksharp]

try function : countc ();

[pre]
data _null_;
freq=countc(' one, two , three ' , ',');
put 'The count number of '','' is ' freq;
run;
[/pre]
