I would like to test whether a card of a given name exists in a stack using hypertalk. There must be an easy way to do this, but I sure can't find anything. My current hack is to do a linear search of the cards in the stack, but this is painfully slow. Have I overlooked a better way? -- John A.

John - Easy. Just go to the card by name, and then look at "the short name of this card". If it matches, it exists. If it doesn't, it doesn't. Yes, a general exists() function would be VERY useful, especially with buttons and fields. -- Raines Cohen SYSOP, BMUG BBS -- INTERNET: bmug!User.Name@apple.COM UUCP: apple!bmug!User.Name

Try: go card foo if the result = "no such card" then beep where foo is the name of the card and beep could easily be replaced with whatever special thing you wanted to do.
