Do while limitations

gjoisa · Nov 25, 2012

This code works

B4X:

        Dim c as Int
        c = 1
   Do While c < 11
      b = c * 4
      c = c + 1
      Msgbox(b,"")
   Loop

But this doesn't work

B4X:

Dim c as Int
        c = 1
   Do While c + 10
      b = c * 4
      c = c + 1
      Msgbox(b,"")
   Loop

and also this Doesn't work

B4X:

Dim c as Int
        c = 1
   Do While c > 9
      b = c * 4
      c = c + 1
      Msgbox(b,"")
   Loop

Why this limitation ?

What do you mean with "doesn't work"?

Your second example contains wrong syntax, as the while condition needs a boolean (and not an int).

In your third example the while condition negates, so that the loop will never run.

In my second example the code should be

B4X:

Do While c = 10

but this code doesnot work .

In which way doesn't it work? c = 1 so it will not enter the block.

Somehow I think you meant to write

B4X:

do until c=10
