I'm trying to add an incremental number to the file I'm saving in the Output_Multiple function because I have the same file running through

multiple outputs with the same file extention. I already have the integer x for the file loop, but don't know how to implement that into the sFile variable

to add the number when saving the file. The data1.dat file is feeding sOutdir and sOutExt.

Any help is appreciated.

Output_Multiple(string sOutput, string sOutDir, string sFile, string sOutExt) //string sExt,
 CAD.SpecifyOutputName.OK.Click()
 CAD.Output.OK.Click()
 CAD.Output.SaveAs.TextField.SetText(sOutDir+ sFile + sOutExt )//sOutExt
 CAD.Output.SaveAs.Save.Click()

testcase Output_Ard () appstate MyDefaultBaseState

 do

   string sTestDir = "BTest\Output_Ard\"
   string sOutDir = sPath+"output.files\"+sVerNum+"\"+sTestDir
   string sGoldDir = sPStart+sTestDir+"Gold\"

   string sOutput
   string sOutExt

   string sFileName

   // start script

   list of FILEINFO lfFiles
   lfFiles = SYS_GetDirContents(sPStart + sTestDir)   
   string sFile
   int x
   for x=1 to ListCount(lfFiles)

      sFile = lfFiles[x].sName
      string sExt
      sExt = Right(sFile, 4)
      if(sExt == ".ARD" || sExt == ".ard")

       do

           OpenDismissDialog(sPStart+sTestDir+sFile)
           //recording

           CAD.SetActive()

           HFILE hfile
           sFileName = (sPStart+sTestDir+"Data1.dat")
           hfile = FileOpen (sFileName, FM_READ)
           while (FileReadValue(hfile, sOutput))

                   FileReadValue(hfile,sOutExt)
                   //FileReadValue(hfile,sOutput)

                   Sleep(2)
                   Output_Multiple(sOutput, sOutDir, sFile, sOutExt) //run standard read from file
                   CloseFileDismissDialog()

except

   WriteIncomplete("Error-Output of {sOutDir + sFile}.cf2 Output failed")
