Help with extending function to work on all open windows

I have written a function to get values from the top window and put them in the command line. But now I wanted to have this function keep track of values in a table for all open windows when the windows are not named in order. Is there a way for Igor to work on traces contained within all opened windows? And how may I keep track of the V_LevelX for each trace in a table? I am having difficulty getting this variable stored in any way except printing it.
Thanks in advance.

Function d()

String wnames =wavelist("*",";","WIN:") //WIN: means top graph
    String name
    Variable i
    wave a
   
 
    for(i =0;i < itemsinlist(wnames);i +=1)
        name = stringfromlist(i,wnames)
        print name
        print rightx($name)
        FindLevel /Edge=2 /Q/R =(2,10) $name ,-0.4; print V_LevelX;
        FindLevel /Edge=2 /Q/R =(15,30) $name ,-0.4; print V_LevelX;
        FindLevel /Edge=2 /Q/R =(31,50) $name ,-0.4; print V_LevelX;
         
    endfor
End
Hi,

The wavelist command can work on windows other than the top window by using the windowName.
"WIN:windowName" Consider all waves in the current data folder that are displayed in the named table or graph window or sub window.

To get the list of windowNames, you can use the WinList command with the specifier
"WIN:windowTypes " Consider windows that match windowTypes and graphs are type 1.

Hi,

You can incorporate Andy's suggestion by enclosing your loop in a loop that goes through the windows, or you can add an argument to you function that takes the window name and then write a separate function that passes window names to your original function.

Instead of printing: a good solution is to make a textwave for your tracenames and then a numeric wave for the values, since you are pulling several values out this should be a 2D wave. Something like:
Function d()
 
String wnames =wavelist("*",";","WIN:") //WIN: means top graph
    String name
    Variable i
    //wave a //don't need this
        Variable nWaves = itemsinlist(wnames)
        Make/O/T/N=(nWaves) labelWave
        Make/O/T/N=(nWaves,4) resultWave
 
    for(i =0;i < nWaves;i +=1)
        name = stringfromlist(i,wnames)
                Wave w0 = $name
        labelWave[i] = name
        resultWave[i][0] = rightx(w0)
        FindLevel /Edge=2 /Q/R =(2,10) w0 ,-0.4
                resultWave[i][1] = V_LevelX
        FindLevel /Edge=2 /Q/R =(15,30) w0 ,-0.4
                resultWave[i][2] = V_LevelX
        FindLevel /Edge=2 /Q/R =(31,50) w0 ,-0.4
                resultWave[i][3] = V_LevelX
 
    endfor
        Edit labelWave,resultWave // show in a table
End

Warning: I've not tested that!
This will give your four values in each column, where each row is a wave in your window.
If you incorporate Andy's suggestion, you'll need to come up with a naming system for the labelWave and resultWave otherwise you'll just end up with the values for the last window the function processes.

Hope that helps
