Current Solution

PROC usage = VOID: printf(($gl$, "Usage: please provide a string"));

PROC longest word length = (STRING s) INT:
    INT longest word len := 0;
    INT word len := 0;
    FOR n TO UPB s
        # If whitespace, reset word length #
        IF isspace(s[n])
            word len := 0
        # Else increment word length and update longest word length #
            word len +:= 1;
            IF word len > longest word len
                longest word len := word len

    longest word len

# Get 1st command-line argument. Exit if empty #
STRING s := argv(4);
IF UPB s = 0

INT longest word len := longest word length(s);
print((whole(longest word len, 0), newline))
