Complex Expression {pos("*",%http%)=1}

[armsys]

When I run the following script, it hangs.

Code: Select all

Let>http=http://www.mjtnet.com/usergroup/posting.php?mode=newtopic&f=2
If>{pos("*",%http%)=1},End
Label>End

Is there any syntax error? Please help. Thanks.

Works fine for me. Doesn't do anything though. The complex The way the If statement is constructed is rather redundant. I realise it is just an example, but I'd do this:

Code: Select all

Let>http=http://www.mjtnet.com/usergroup/posting.php?mode=newtopic&f=2
Let>x={pos("*",%http%)}
If>x>0
  //do whatever here if * is found in URL
Else
  //do whatever here if no match
Endif

Hi Marcus,
Thanks for replying my post in seconds. Later I'll run the MS debug to identify the cause of the hang. Actually, another similar code:
If>{length(%http%)=0},End
runs perfectly. Then, the immediately next line:
If>{pos("*",%http%)=1},Skip
causes Macro Scheduler to pause indefinitely.
Maybe it's caused by hidden/illegal characters.
Thanks for your help.

Now the debugger shows If>{pos("*",%http%)=1},Skip actually jumps to Until>k,20 if HTTP doesn't contain "*". But why? Is it supposed to go to the next line, that is, If>k>1?

Code: Select all

Repeat>k
  WaitReady>0
  Let>k=k+1
  Let>http=http[%k%]
  If>{length(%http%)=0},End
  If>{pos("*",%http%)=1},Skip
  If>k>1
    Press Ctrl
    Wait>.1
    Send>t
    Release Ctrl
  Endif
  WaitWindowChanged>2
  WaitWindowOpen>Blank Page*
  WaitReady>0
  Wait>1
  Press BACKSPACE
  Wait>.2
  Send>%http%
  Wait>.2
  Press Enter
  Wait>.1
  Label>Skip
Until>k,20

hmmmm .. not sure why that's happening. I'll investigate further. But in the mean time you could do as I suggested above:

Let>x={pos("*",%http%)}
If>x=1,Skip

I'm confused by:

If>k>1

maybe the script is too

Hi Me_again,

That line if OK, as long as it has a matching endif, and it does:

Code: Select all

If>k>1
  Press Ctrl
  Wait>.1
  Send>t
  Release Ctrl
Endif

Its very similar to an example for the If command in the Help File only it doesn't use an ELSE:

Code: Select all

Let>a=5
//simple expression only
IF>a=5
   //do something
ELSE
   //do something else
ENDIF

The first > is part if the If> command itself so that line just reads... "if k is greater than 1".

You're right, I was thinking in another language

Hi Me_again,
In case if you're interested, the purpose of the script is to fire up multiple tabs in IE7.

Hi Marcus,
After multiple tests and through logical reasoning, I definitely believe that pos() is buggy.
Yes, your suggested code Let>x={pos("*",%http%)} works faultlessly.

However, for If>{pos("*",%http%)=1},Skip, even though the condition is false, that's, the http string doesn't contain "*", the true_label_name, that's, Skip, is still chosen. But why? My guess is the comma (,) inside Pos() confuses Macro Scheduler interpreter.
If>{pos("*",%http%)=1},Skip,End will pop up fata error:
Line: 50 Error - Subroutine/Lable Skip,End Not Found!
Hope you find the info useful.

Hi Marcus,
MS 10.1.01 fixes the issue. Thanks a lot.
