Using arrays and For loops

[Eli_jahbot]

My esteemed Autoits I need your help once again.

I'm trying to figure out how to create a loop that gets 1 value from an array and repeats until each value from the array has been used. I have never used arrays before and I know once I learn more things should get easier for me. 

Here is what Im trying to do:

-Have an array of values that determine what application i log into. ex: app1, app2, app3, app4 etc.

-Have a loop that repeats a process sequentially using each value in the array to finish the process for each app1, app2, app 3 and so forth. I have 30 apps that I need to update on a regular basis and getting this sorted out is what I perceive to be the best way to do it.

Here is my feeble attempt that obviously fails:

#include <msgboxconstants.au3>
#include <Constants.au3>
#include <array.au3>

Login()
Func Login()
    local $array[30] = ["10", "11", "12",etc etc]
    ;;Local $site = InputBox("ERx Site","What site do you want to login as?","","")
    Local $userid = InputBox("ERx Login", "What is your username?", "", "")
    Local $Passwd = InputBox("Security Check", "Enter your UAT password.", "", "*")

for $1 = 1 to 30(I need to do the same steps in 30 different apps)
run("Z:launch.exe")
WinWaitActive("Input")
Send (Sequential ARRAY VALUE HERE)
Send("{ENTER}")
WinWaitActive("window")
Send($userid)
Send("{TAB}")
send($Passwd)
Send("{ENTER}")
WinWaitActive("[CLASS:SunAwtDialog]")
Sleep(500)
WinClose("Home Page")
Next
EndFunc
 

your help is greatly appreciated.

Thanks for your time
