Example 1: Returning String Lengths

The following statements find the lengths of character strings and text expressions.

%let a=Happy;
%let b=Birthday;

%put The length of &a is %length(&a).;
%put The length of &b is %length(&b).;
%put The length of &a &b To You is %length(&a &b to you).;

Executing these statements writes 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.
