Android Question single line multi commands

sorex · Jan 26, 2014

Hello,

In several languages I can do this:

B4X:

If myvar="" Then showalert:Exit

the B4A precompile pass doesn't give an error on this
but during the java compile it gives this error

B4X:

src\b4a\example\main.java:323: error: break outside switch or loop
if (true) break;
          ^
1 error

using exit sub also fails.

ain't there a way to get this working without all the extra linefeeds and end if's ?

ok, it seems that I had to use return instead of the exit method like in VB and others.

In B4A/J the following code:

B4X:

If myvar="" Then showalert:Exit

Is equivalent to:

B4X:

If myvar = "" Then showalert
Exit 'not inside the if condition.

You cannot combine two statements this way.
You will need to write:

B4X:

If myvar="" Then
 showalert
 return
End If

Indeed, I noticed it when my 2nd check didn't work.
