Scripting a text to binary digits converter

[Michael Doub]

How's this?

Function convertBinaryToText varText
   repeat with x = 1 to the len of varText-8 step 8
      put numtochar(BaseConvert(char x to (x+7) of varText,2,10)) after tConverted
   end repeat
   return tConverted
end convertBinaryToText
