The "next" keyword

I thought that the next keyword was the BrightScript equivalent for, say, Java's continue. But, it turns out that it is equivalent to end for. Why ?

1. Every keyword K, which begins its own scope - function sub, if, while, for - ends with end K. Why an additional synonym for end for ?
2. Does this also mean BrightScript doesn't have anything equivalent for Java's continue ? Like exit for is the equivalent to Java's break ?

    Brightscript is more similar to BASIC, where For is always followed by a Next:

    for i=0 to 100
    print i
    next i

    for each element in array
    ?element
    next


    (notice, you don't reference the variable name in a for each)
    However Next is deprecated in favor of End For

    for i=0 to 100
    print i
    end for

    for each element in array
    print element
    end for



    There is no continue. There is a goto statement which can jump to labeled code:
    sub main()
         for i=0 to 100
              if i=50 then 
                   goto somewhere
              end if
         end for
    somewhere: 
         print "i=";i
    end sub


    Generally, using goto statements is not recommended.
