This is my code:

------------------ start ------------

function cekPrima(sequence bilPrima, atom cekangka)
atom isilist

        for j=1 to length(bilPrima) do
            isilist=bilPrima[j]
            if (cekangka/isilist - floor(cekangka/isilist))=0 then
                --bukan bil prima
                return 0
            else
                --bilprima
                if power(isilist,2)>cekangka then
                    return 1
                end if
            end if
        end for
        
        return 1

end function

sequence p
p = {2, 3}

for i = 3 to 10000 by 2 do
    if cekPrima(p, i)=1 then
        p &= i
    end if                   
end for 

? p

integer pos
integer jum

with trace
trace(1)

for i=2 to 100000000 do
        pos = 1
        jum = 1

        while 1 do
                if p[pos] > sqrt(i) then
                        exit
                elsif p[pos] = sqrt(i) then
                        jum += p[pos]
                else
                        pos += 1
                        if integer( i/p[pos] ) then
                                jum += i/p[pos] + p[pos]
                        end if
                end if
        end while
        
        if jum = i then
                ? i
        end if
end for

------------------------- end ----------------

Execute, and it will bring a trace window.

Highlighted: for i=2 to 100000000 do

Press DOWN. (don't press ENTER)

Press ?i

"i=9999" is displayed on left side??? it should be 2.

Press ENTER many times until "end for"

Press ENTER one time more.

"i=9999" in the left disappears, "i=3" appears in right side.

Press ?i

"i=3" in the right disappears, "i=9999" appears again in left side.





Is this really a bug?!
