I think their is a bug in the go command! ver. 1.2.5 One can use the go command to move to a card by specifying either the card's number or id or name. if one uses: go to card numberX then one moves to card number numberX go to card "nameX" then one moves to card named nameX Now, the bug is when one uses a number in the name field so that the name of the card is for example "14". so if one says: go to card "14" it doesn't go to card named "14" but instead it goes to card number 14. (assuming their aren't the same cards) so that (go to card "14") behaves just like (go to card 14) this looks like a bug to me. right?? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /\ ! ~~~~Hayaa Ala-falaah Abdennour Moussaoui || _~_~_ Allahu Akbar Allahu Akbar Oregon State University ||(_____) Laa Illaha Ila Allah~~~~ email=abdenour@mist.cs.orst.edu |||_|_|_|

There is NO DISTINCTION between "14" and 14; they are identical for all purposes in Hypertalk. When you say "go to card xyz", it evaluates xyz; if it's a number, Hypercard assumes you mean the card number; otherwise, it tries for a card with that name. Moral: don't give cards names which are numbers. There are some other really strange effects of Hypercard's "programmer-friendly" design: "book" = "Book" evaluates to true "book" > "Book" evaluates to true "book" <= "Book" evaluates to false That's because >, <, >= and <= all mean arithmetic comparison, where ASCII 'b' is after ASCII 'B', while '=' (or "is") means textual comparison, which is case-insensitive.
