numerically sort wave list

Hi,

I have waves such as: wave001_411, wave002_411, ..., wave999_411. I want to sort the "Wave List".

I use:
#pragma rtGlobals=1     // Use modern global access method.
#include <WindowBrowser>
Function ali()
    String Vx_list = WaveList("dVdI*_Vx_1011", ";", "")
    Make/N=63 textwave
    Variable nwaves = ItemsInList(Vx_list)
    textwave=stringFromList(0,Vx_list)
    Edit textwave
    Sort textwave,textwave
    print textwave
end

but I get an error, IGOR does not recognize stringFromList...And actually I am not sure if the above is what I need. All what I need is to sort Vx_list.

Is there any way to do this? i.e. to let IGOR sort based on the first number part in the file names?
Try:
#pragma rtGlobals=1     // Use modern global access method.
#include <WindowBrowser>
Function ali()
    String Vx_list = WaveList("dVdI*_Vx_1011", ";", "")
    Variable nwaves = ItemsInList(Vx_list)
    Make/O/N=(nwaves)/T textwave // you forgot the /T
    textwave=stringFromList(p,Vx_list) // your version got only the first element from the list
    Edit textwave
    Sort textwave,textwave
    print textwave
end

instead.

Same thing. "Unknown/Inappropriate name or symbol". Although I successfully use StringFromList in another place within the same procedure.

Is this, anyway, I will need to convert the new text wave into a string. How to do that?

EDIT: Yes, /T solved the problem.

Now, how can I convert the text wave back to a String to use it in place of the unsorted list Vx_List ?

#pragma rtGlobals=1     // Use modern global access method.
#include <WindowBrowser>
Function ali()
    String Vx_list = WaveList("dVdI*_Vx_1011", ";", "")
    Make/N=63 textwave
    Variable nwaves = ItemsInList(Vx_list)
    textwave=stringFromList(0,Vx_list)
    Edit textwave
    Sort textwave,textwave
    String list= TextWaveToStringList(textwave)
    print list
end

Function/S TextWaveToStringList(tw)
    Wave/T tw
   
    String list=""
    Variable i, n= numpnts(tw)
    for(i=0; i<n; i+=1 )
        list += tw[i]+";"
    endfor
   
    return list
End


HOWEVER, why not just use SortList on the original WaveList result?
