filter and reorder a list via field on other stack

[Sivakatirswami]

Well, if there is any textual relationship between the actual content 
of the line on the list and the card itself, then I have (ever since 
hypercard and supercard days) *always* named my cards programatically 
and then using the clicktext function on the index listings:


go to card (the clicktext) # in the index list field

or

go to card (word 1 of the clicktext)

or whatever...it will always work regardless of a) sort order of the 
list b) sort order of cards in the stack...

the trick is to have the cards get their name assigned the name you 
want that will relate to the index list, at the time those card are 
created... and then dynamically generate indices from the card names... 
there are caveats though... I can't remember them all.. I think you 
don't want to start a card name with a number...?? I typically have a 
short field on every card in my PIM

subject:

and a close card handler: "set the name of this card to fld "

Here is how I hyper link and generated cards from selected text and 
auto add to an index:

on makeLink
   if the selection is empty then
     answer "You need to select something." with "OK"
     exit makeLink
   else
     put the selection into tNewCard
     set the textstyle of the selection to link
     open stack "Linked Entries"
     if exists (card tNewCard)  then
     exit makeLink
     else
    new card
     put tNewCard into fld "Subject"
     set the name of this card to fld "subject"
     send upDateIndex to stack "linked Entries"
     end if
   end if
end makeLink

on upDateIndex
repeat with x = 1 to the number of cards of this stack
     put short name of cd x & cr after tIndex
   end repeat
   sort tIndex
   put tIndex into fld "index"
   choose browse tool
end upDateIndex

And here is a dynamically built index put into a button, but you could 
adopt this to create the index into a field, incredibly simple 
really....

Pull down menu button:

on mousedown
   repeat with x =1 to the number of cards in  this stack
     put the short name of card x & cr after jai
   end repeat
   put jai into me
end mousedown
on menupick which
go to card which
end menupick

And don't forget one of those xTalk gotchas:

"the short name" gives you a simple string, but you never set the short 
name you just "set the name"

set the short name of this card to "Go Figure"

gives an error. On day they should fix that...

I've had stacks with thousands of cards, all named and going to a card 
name is very fast.
