I just found a bug:

Code: Select all  Expand view

FUNCTION MAIN()

    LOCAL i

    FOR i = 1 TO 10
        FOR i = i TO 5
            ? i
        NEXT
    NEXT

    INKEY( 0 )

    RETURN NIL

Code: Select all  Expand view

BUG.prg(6) Warning W0030  Duplicate variable 'I' in nested FOR loop

No code generated.

Enrico,

I don't think that is a bug as it is reported as a warning

Anyhow the right place to report it is in the Harbour developers group at:
https://groups.google.com/forum/#!forum/harbour-devel

thanks

Still I think it's a bug. Anyway, is there a way to suppress it?

It would be wasted time, you know.

Ni idea how to supress that warning...

Regarding reporting it, you will never know it unless you try it

I already tried it in the past. And I really have enough of them. Sorry.

Enrico,
In this case, it would not be ideal to separate the variables

Code: Select all  Expand view

FUNCTION MAIN()

    LOCAL i,ii

    FOR i = 1 TO 10
        FOR ii = i TO 5
            ? ii
        NEXT ii
    NEXT i

    INKEY( 0 )

    RETURN NIL

It was only a sample. The point is that there is no valid reason to issue a warning in this case and no compiler in any language issues it.

Other compilers do not warn that their code produces an endless loop?
I prefer that the compiler warn me

No, why should it be? Endless loops are useful sometimes. Anyway, neither Harbour warns on that. It warns the use of the same index variable in nested loops.
