Several forum contributions quoted "position" formulations containing variables for occurrences.  I am at a loss why my simple script (FM 17, win10) containing a loop (stepwise increasing $i) which includes

Set Variable [$colon[$i]; Value: Position ( Filme::Besetzung; ":"; 1; $i)]

doesn't yield any result - unless I use numbers rather than the variable, testwise. (I wonder how to paste lines from the script here.) I assume I made an amateurish mistake and am looking forward to receiving advice of someone more experienced.

You can print the script to PDF and copy/paste from there. Or - much better - post a small file that shows the problem (and nothing else).

 

thanks! I'd love to follow your advice, but could only do the pdf attachment. How to post the script? Sorry, I'm new here...

I don't detect anything wrong with the script (other than that it doesn't do anything with the variables it populates). But that could be because I am reading the script, instead of running it. How did you determine that it "doesn't yield any result"?

Thanks! In this part of the script, I meant to set $colon[1...$i] to contain the positions of ":" in the text "Filme:Besetzung", and $absatz the respective positions of the paragraph symbol.When I run data viewer in watch mode, $a and $i are correctly displayed, but nothing is given for $colon[$i] or $absatz[$i] unless I explicitly watch $colon[3], for example, to check the basic formulation, and then get the correct position number I counted in the text. It seemed so simple...

I am afraid I cannot reproduce the problem you report. I am attaching a simple file I made. In the last pause of the script, I see this in the Current pane of the Data Viewer:

and this in the Watch pane:

More thanks! I restarted FM, and the computer, but both didn't help. Please find attached screenshots of the data viewer for loop runs 1 through 4. For now, I give up...

I am afraid this is not moving us forward. Did you run my file? What results did you get? 

OK! Now I tried it, and everything appears to be fine; same results as you showed. Can you possibly suggest anything else (apart from reinstalling the software)?

More news: I ran the script on my old win7 PC, and it worked perfectly. Thus, I reckon I'll have to reinstall FM17, after all - but thanks anyway for your help and patience!

After updating to 17.0.7.700, everything is fine. Grateful greetings and best wishes!

I am glad you got it sorted. As an aside, I am not sure what exactly you're trying to accomplish here, but I suspect there is a simpler way.

 

Yes, probably you're right! In the text field the script is meant to work on, each line contains an actor's name, and the respective character in a movie, arranged in various ways, e.g. separated by a specific word ("as") or a colon, or with brackets around the characters. Sometimes, the names are first, sometimes the characters. I want to extract the names only and put them in a repetition field. (I know, users are discouraged to apply this feature, but I'd like nevertheless to keep this structure, rather than unravel and reorganize it.) The entire script has grown over time, with ever more versions of how names and roles are assembled in the movies' informations; that is why it certainly is somewhat discombobulated.

I too would recommend against using a repeating field for this. Splitting lines of text into separate related records is very easy, and you don't need to create repeating variables or find the positions of carriage returns for this. Just do something like:

Set Variable [ $n; Value:ValueCount ( YourTable::Textfield ) ] 
Loop
Set Variable [ $i; Value:$i + 1 ]
  Exit Loop If [ $i > $n ]
  Set Variable [ $line; Value:GetValue ( YourTable::Textfield ; $i ) ]

At this point the $line variable will hold the current line and you can go to the child table, create a new record and populate the name field with the name extracted from the $line variable. I am not sure how exactly to do the extraction, since you've listed several options but did not provide any rules for distinguishing among them. 

 

Very kind of you, thanks! I'll let you know when the project is successfully finished!
