I have in a service this code:

dim a as int
dim b as int

for a =0 to 10

for b=0 to 10
next b
next a

And when start the application using this code as service ocurrs an error.-

If i change 1 for with DO WHILE, the code is ok.-

I can think that this problem is a bug in the compiler?

thanks-

Hello,

You can not use the variable's letter in your Next. It should be only Next

B4X: 
Dim a as Int ' this could be omitted
Dim b as Int ' this could be omitted

For a=0 to 10

  For b=0 to 10
    Log("a: " & a & "/" & "b: " & b)
  Next

Next

PS: in your IDE's options, you could check "Test compile when saving". It would have shown the error before you spend the time to try

No. It is like it is described int he documentation.

But you can write it like this to help you seeing which for-loop you are in.

B4X: 
Dim a as Int ' this could be omitted
Dim b as Int ' this could be omitted
For a=0 to 10
  For b=0 to 10
    Log("a: " & a & "/" & "b: " & b)
  Next ' b
Next ' a

Thanks Manfred.

I can also write a more descriptive string (Next ' c - customer) but an automatic insertion would be useful:
I write:
For A = ...
and pressing Enter
Next A (case sensitive too)

Yes, that would be great
