Map

Is this the expected behavior? shouldn't the last element have remained unchanged when exiting the loop?

Code: Select all

NewMap Country.s()

Country("GE") = "Germany"
Country("FR") = "France"
Country("UK") = "United Kingdom"

Debug "good "+Country()

ForEach Country()
   Debug Country()
Next

; ResetMap(Country())
; NextMapElement(Country())

Debug " badly "+Country()

No.

After a ForEach Map or List the pointer is always behind, else the loop is not finished.
Never is the last element selected.

I don't agree with you. This is the expected behavior for me.

Code: Select all

NewList Country()

AddElement(Country())
Country() = 1
AddElement(Country())
Country() = 2
AddElement(Country())
Country() = 3

Debug "good "+Country()

ForEach Country()
   Debug Country()
Next

Debug " good "+Country()

If I follow your opinion, the following code should show 9

Code: Select all

For i = 0 To 9
Next i

Debug i

But it shows 10, which is behind the loop counter.

You can try to place a bug report about this

I often use if and break inside loops and detect behind the loop
if the loop was 'normally' finished or 'breaked'
With a normal For you can check if the vaiable is higher then the last wanted value.
With a ForEach you can check this if an element is selected.

The behavior is correct with ForEach, because the loop ends when there is no more current element

Why does this behavior not belong to the "list"?
in this regard, I had to add this.

Code: Select all

; bug PB
            If MapKey(roots( )) = ""
               ResetMap(roots( ))
               NextMapElement(roots( ))
            EndIf
