Description
The length() function returns the length in characters of text, including new lines. This function differs from num_bytes(), which returns the length of a string in bytes. Due to international codesets, one or more bytes can form a single character.
Example
The following length() function call returns the number of characters in a string:
X = "28 characters in this string";
List = ["red", "green", "blue"];
print(length(List), " Length of list\n");
print(length(X)," Length of string \n");
List = ["red", "green", "blue"];
print(length(List), " Length of list\n");
print(length(X)," Length of string \n");
