Re: repeat for each....

[Klaus Major]

Hi Mark

This is driving me barmy...
Again i learned a useful english word ;-)

can any kind soul here explain why this works:

on tryLoopWith
  put "a,b,c,d,e,f" into charList
  repeat with n = 1 to the number of items in charList
    put item n of charList into line n of newCharList
  end repeat
  put newCharList && "with"
end tryLoopWith
but this throws up a 'bad chunk expression" :

on tryLoopFor
  put "a,b,c,d,e,f" into charList
  repeat for each item n in charList
    put item n of charList into line n of newCharList
  end repeat
  put newCharList && "for"
end tryLoopFor
"repeat for each..." is a read-only thingie... ;-)
Means that "n" in this case will not hold the number of the current 
line as in "repeat with...",
but the CONTENT of "the current line of charlist"...

So there is no "line n of newCharList".
(The engines sees: line "a" of newCharList...)
...and there is no such thing as "item n of charlist".
(And here: item "a" of charlist...)
That's why you get an error...

Try to create an extra counter for this purpose.
Even with a counter the "repeat for each..." loop is still insanely 
fast :-)

on tryLoopFor
  put "a,b,c,d,e,f" into charList
  put 1 into mycounter
  repeat for each item n in charList
    put n into line mycounter of newCharList
    ### just pure n :-)
    add 1 to mycounter
  end repeat
  put newCharList && "for"
end tryLoopFor
I haven't yet been able to make the 'repeat for each...' structure 
work at all, not even once,
in any circumstance, in a year of trying it from time to time.
It is a bit tricky, indeed...

I can find nothing in the electronic docs to help me. I am mystified.
I am sure we will be able to guide you into the right direction ;-)

TIA,  Mark Smith
Hope that helps...
