Understanding of AutoIt variables

[n4n0]

Hi! I am pretty new with AutoIt, and wanted to ask help about the script, but managed to make it work myself. I am not sure why it works so I wanted to ask why and how it works as it does. Here's the script:

 

 

HotKeySet("{PGDN}", "ExitIt")

HotKeySet("{PGUP}", "JustAnotherFunc")

 

Func ExitIt()

Exit

EndFunc

 

$aa = 0            ; Why can't I just use 0 in While ?

$bb = 101        ; The start of numbers sent

$cc = 300         ; Where the numbers stop after 1-step

 

Run("notepad.exe")

 

WinWaitActive("Untitled - Notepad")

 

Func JustAnotherFunc()

While $aa < $cc                      ; Why and how does it work?

Send($bb + 1)                        ; 1-step spam up to $cc

Send("{ENTER}")

$bb = $bb + 1

$aa = $bb                               ; The script continues infinite without this line. Why?

WEnd

EndFunc

 

While 1

Sleep(100)

WEnd

 

 

Thanks in advance.

See additional comments below:

HotKeySet("{PGDN}", "ExitIt")
HotKeySet("{PGUP}", "JustAnotherFunc")
 
Func ExitIt()
 Exit
EndFunc
 
$aa = 0           ; Why can't I just use 0 in While ? ***You could, but then it will loop forever***
$bb = 101         ; The start of numbers sent
$cc = 300         ; Where the numbers stop after 1-step
Run("notepad.exe")
WinWaitActive("Untitled - Notepad")
Func JustAnotherFunc()
 While $aa < $cc     ;Why and how does it work? ***You are saying, Run this loop as long as $aa is less than $cc***
  Send($bb + 1)   ; 1-step spam up to $cc
  Send("{ENTER}")
  $bb += 1     ;***More compact than $bb = $bb + 1***
  $aa = $bb       ;The script continues infinite without this line. Why? ***Without this line, the value of $aa (0) never changes, so it will always be less than the value
      ;of $cc, and the loop never ends.
 WEnd
EndFunc
While 1
 Sleep(100)
WEnd

 

You could also do something like this to shorten things up:

HotKeySet("{PGDN}", "ExitIt")
HotKeySet("{PGUP}", "JustAnotherFunc")
Func ExitIt()
 Exit
EndFunc
$bb = 101
$cc = 300
Run("notepad.exe")
WinWaitActive("Untitled - Notepad")
Func JustAnotherFunc()
 While $bb < $cc     
  Send($bb)      
  Send("{ENTER}")
  $bb += 1     
 WEnd
EndFunc
While 1
 Sleep(100)
WEnd

Welcome to AutoIt and the forum!

To get a better understanding of how variables work in AutoIt I suggest to read the wiki.

Thanks a lot for the answers!

Also, how do you insert a script like this?

You mean to insert the script into the thread with formatting and colouring?

Use the AutoIt icon (the blue A) in the editor and insert your code.
