I have only a small experience with AHK and I can normally get the right statements working but this has stumped me. I know it should bite me but it will not.
I am after the ascii number
List ="ABCD"
msgbox, Asc, List
To give the ascii of "A"
I have left it in this form knowing I am wrong. I have tried putting % everywhere. all I get is the string name not contents.

ie how do I display the value of Asc, List or Asc(List)

While I still have hair

1st break it up, each character has its own ascii value.

Code:

List = ABCD
stringSplit, chr, list
loop % chr0
  ascList .=  chr%a_index% " " asc( chr%a_index% ) "`n"

msgbox % ascList

I think you may have overthought this one, TLM :wink:

Code:

List = ABCD
Loop, Parse, List
   ascList .=   A_LoopField " " Asc(A_LoopField) "`n"
MsgBox % ascList

I also avoid the possibility of trying to explain StringSplit and dynamic variables as a follow-up discussion. I prefer only the laziest of solutions. :wink:

Wow Thanks to all. Can you believe I was up till 1am this morning and did not get it.
TLM Yes I do have trouble with the way I reference variables.
The help file shows either asc(string) or asc, string
so I tried asc(List) and asc, List. which should give the ascii number of the first letter So I was stumped. I would appreciate that explained according to the help file the correct way of displaying msgbox, asc(List)
I never tried
msgbox % ascList
I will hang on to what hair I have left

I cannot find the explanation for .= I have for :=

Also I do not understand why. Extract from help file

Quote:

Asc(String): Returns the ASCII code (a number between 1 and 255) for the first character in String. If String is empty, 0 is returned.

does not work for
List = ABCD
msgbox, Asc(list) or msgbox, Asc(%List%)

I must be thick I did try your codes and see how they work but not equated to the example above.

Just look at it as a way to "grow a variable". To see the step by step growth, run this

Code:

loop 10
  msgbox % growingvariable .= a_index " "

msgbox % growingvariable .= "`nNow some text.`n"

msgbox % growingvariable .= "And yet even more.`n"

msgbox % growingvariable .= "As you can see.`n"

msgbox % growingvariable .= "It just keeps growing.`n"

I will wish you all a very G'Day

I am trying to total ascii numbers which you showed me how. But how do I add these together to get a total.
I am trying

Code:

; array from above
while(x< List+1){
A.=   asc( chr%x%); This gives the ascii number at each iteration
; I cannot get the code to work to add the numbers for each iteration here To finish with all the ascii numbers of the letters in the list totaled together
x++
}

I have difficulty getting the referencing to work. I am so used to Basic and this syntax is trying.

Code:

I agree the syntax is something to get used too

Maybe:

Code:

list=abcd

Loop, Parse, List

{
asc_sum += Asc(A_LoopField) 
asc_debug .=Asc(A_LoopField) "|"

}

msgbox %asc_sum%  `n%asc_debug%

thank you Thanh00 , very short, I used TLM's code, example add ascii code

Code:

List = ABCD
stringSplit, chr, list
x:=0
y:=0
loop % chr0
  {
  ascList .=  chr%a_index% " " asc( chr%a_index% ) "`n"
  x:=asc(chr%a_index%)
  y:=(x+y)
  }
msgbox %ascList%`nTotal=%y%
return

In this case only X has to be declared

Code:

List:="ABCD", x:=!!x ; init to true
stringSplit, chr, list
while chr%a_index% ; Alternative loop method if theres no auto array
  ascList .= chr%a_index% " " (y:=asc(chr%a_index%)) subStr(x+=y,1,0) "`n"
msgbox %ascList%`nTotal=%x%
