#length

##Syntax length ( s : string ) : int

##Description The length function returns the number of characters in the string. The string must be initialized. For example, length("table") is 5.

##Example This program inputs three words and outputs their lengths.

If the words are "cat", "robin" and "crow", the program will output 3, 5 and 4.

    var word : string
    for i : 1 .. 3
        get word
        put length ( word )
    end for

##Details The length function gives the current length of the string. To find the maximum length of a string, use upper. For example, given the declaration var s : string (10), upper (s) returns 10.
