%KLENGTH (character string | text expression)

If the argument is a character string, %KLENGTH returns
the length of the string. If the argument is a text expression, %KLENGTH returns
the length of the resolved value. If the argument has a null value, %KLENGTH returns
0.
The following statements
find the lengths of character strings and text expressions:
%let a=Happy;
%let b=Birthday;
%put The length of &a is %klength(&a).;
%put The length of &b is %klength(&b).;
%put The length of &a &b To You is %klength(&a &b to you).;
When these statements execute, the following is written to the SAS log:
The length of Happy is 5.
The length of Birthday is 8.
The length of Happy Birthday To You is 21.
