problems wirh chr()

[dainsleif 0]

hi all

i am trying to code a function that reads triplets of nubers out of a string ($klartext) with the length $anzahl and converts them to chars

the function works as far as (means i'm getting the expected triplets)

$klar=stringtrimright($klar,stringlen($klar)-3)

but it won't convert the number into char

func konvtotxt($klartext,$anzahl)
 $klartxtout=fileopen("decrypt.txt",1)
 if mod($anzahl,2)=1 then
  $anzahl=$anzahl+1
 endif
 for $i=0 to $anzahl/3
  $klar=$klartext
  $klar=stringtrimleft($klar,$i*3)
  $klar=stringtrimright($klar,stringlen($klar)-3)
  $klartxt=chr($klar)
  filewrite($klartxtout, $klartxt)
 next
 fileclose($klartxtout)
endfunc

any ideas?

What are the values you are passing to CHR? Are they all numeric? Please provide a sample of how you are calling to the konvtotxt function (including the values for its parameters).

Func konvtotxt($klartext,$anzahl)

 $klartxtout=FileOpen("decrypt.txt",1)

 If Mod($anzahl,2)=1 Then
  $anzahl=$anzahl+1
 EndIf

 For $i=0 To $anzahl/3
  $klar=$klartext
  $klar=StringTrimLeft($klar,$i*3)
  $klar=StringTrimRight($klar,StringLen($klar)-3)
  $klartxt=Chr(Int($klar))
  FileWrite($klartxtout, $klartxt)
 Next

 FileClose($klartxtout)

EndFunc

Try the above modified code and let me know how it turns out. I also made your code a bit more readable.

this code works now! thx a lot..

seems as if the only thing missing wass the explicit conversion to int

the string passed to the function was 049050 in my testcase..
