Ok, this question it very simple just any one example.

I whant read one external file (Data.log). This file have four column and many lines like this.:

    First Name        Last Name     Movielphone            HomePhone
         Peter             Gomez     (305)555-5555        (305) 444-4444
         Anni              Gomez     (305)555-5555        (305) 444-4444

In this script have four variable   First Name, Last Name, Movielphone and  HomePhone. I need to read all value in my external file for create other process.
Example.:

WshS.run ".\delprofi.bat " & First Name & Last Name & Movielphone & HomePhone

Thanks

You can use the Windows Shell Runtime, using the FileSSystemObject:

Dim fso

Set fso = CreateObject("Scripting.FileSystemObject")

you can learn about how to use the FileSystemObject at this Microsoft link:

Does This Work
------------------------------Untested ...Very Busy today

Const objDBlist = "C:\text.txt"
Const ForReading = 1
Const BatchFile = "C:\Batch.bat"

Public LastName(),FirstName(),Movielphone(),HomePhone()
x=0
Set Wshell = CreateObject("Wscript.Shell")
Set objTextFile = objFSO.OpenTextFile(objPClist, ForReading) '1 ip or hostname per line
      Do Until objTextFile.AtEndOfStream
            strLine = Split(objTextFile.readline,VBtab)
            
            ReDim Preserve FirstName(x)
            ReDim Preserve LastName(x)
            ReDim Preserve Movielphone(x)
            ReDim Preserve HomePhone(x)
            
            LastName(x)= strLine(0)
            FirstName(x) = strLine(1)
            Movielphone(x) = strLine(2)
            HomePhone(x) = strLine(3)
            
            x = x + 1
      Loop
      
For z = 0 To (x -  1)
      Space = " "
      Arguments = Space & Firstname(z) & Space & LastName(z) & Space &  Movielphone(z) & Space & HomePhone(z)
      Wshell.Run (BatchFile & Arguments)
Next

A couple things about this script....
1) It assumes that these fields are seperated by TABS
2) If there is an empty line in your file ... It will blow up
3) If the files dont exist, it will blow up
4) If the user doesnt have permission to the file it will blow up
5) If there is a line with a missing entry it will blow up
6) If you strap a bomb to it, IT WILL BLOW UP!!!

No, if none of those situations were met then it is something unaccounted for.
Tell me your line 21 so I can sync up with yours.

If it is where i think it is then double check these:

1) It assumes that these fields are seperated by TABS
2) If there is an empty line in your file ... It will blow up

Get some skis and jump dude?!?!  I am unsure of what you want here. If there were errors or problems you could give the experts chances to fix them and if you dont its on you.  On the other hand if i have completely misunderstood your comment I am sorry.
