MsgBox($MB_SYSTEMMODAL, "", "The 3 leftmost characters are: " & $sString)
$sStringBeta= StringReplace ($sString, "  ", "" )


Local $a = 0         ;Loop counter variable
Do
    $a += 1       ;Adds 1 to the loop counter
    Send("INSTANCE " & $a & "{ENTER}")
    Sleep(1000)          ;Waits
 Until $a = $sStringBeta                  ;How many times to loop

 

Thank you for your help. Much appreciated

#include <MsgBoxConstants.au3>

;$file = "C:\Users\Charlie\Desktop\t.txt"
$file = @ScriptDir & "\T.log"    ;This is the log file which is read in real time

; The following Reg Exp finds
; the last occurrence of a line (".*" is greedy by default)
; beginning with spaces (if they exist) ("^\h*")
; followed by 1 to 3 digits ("\d{1,3}").
; Those 1 to 3 digits are captured ("(\d{1,3})").
; See AutoIt help file for explanations of "(?s)" and "(?m)" PCRE patterns. Explains how "." and "^" are affected.
$iNum = StringRegExp(FileRead($file), "(?sm).*^\h*(\d{1,3})", 1)[0]
ConsoleWrite($iNum & @CRLF)

WinActivate("My Application")
Local $hWnd = WinWaitActive("My Application", "", 5)

If $hWnd Then
    For $i = 1 To $iNum
        Send("DISPLAY LIST")
        Sleep(2000)
        Send("{ENTER}")
        Sleep(5000)
        Send("INSTANCE " & $i & "{ENTER}")
        Sleep(1000) ;Waits
    Next
Else
    MsgBox(0, "", '"My Application" window not found.')
EndIf

I have run into a snag. Data to the logfile is added after the Send("DISPLAY LIST"). The number of times to loop is unknown till Send("DISPLAY LIST") is sent. How can we first perform Send("DISPLAY LIST"), which generates the log file and then use the loop counter from the log file for the following formats
