>I need a function CardExists(cardName).

   There is a real simple way to do this. HyperCard now returns all
errors in the result. So you can "go to card cardName" and if the
result is "no such card" then handle it appropriately.

>HyperMedium as an intruction manual.

   I think the tutorial for Migent's In-House Accountant was one of
the first to be done in HyperCard. There are many people doing this
now including Claris! As for instructions on something other than
a software program, try Kinkos Academic Courseware Exchange for
stacks on various topics.

>Trapping keypresses.

   Guy de Picciotto's INKEY external command works great. It is available
on most services. You can find it and many other external commands
in my XCMD Register stack. Send me a disk and a SASE and you'll get it free.

>Unexpected error 54321 and "Sorry"

   This usually happens when you are playing with the "debug writeon"
and "debug writeoff" commands that are undocumented commands in
version 1.1 ONLY. They turn writing to the disk on and off. Make sure
those commands are not in your stack anywhere. A good way to check would
be to run the stack under 1.2 and wait for "Cant understand debug"
to show up.

>Miniature sized set of relevant cards

   Copy a card, and when you choose Paste, hold down the command and
option keys (I believe). Those may not be the exact keys, but it is
a combination of command/shift/option while you are choosing Paste.
That will put a miniature picture of your card on the screen. You
can easily write a script to paste many of them onto a blank card.
I will post the code if you like.

>Printing on the IISC from HyperCard 1.2

   There is a bug in HyperCard version 1.2 that will not allow it to
print on the LaerWriter IISC correctly, or sometimes at all. The
only solution is to upgrade to HyperCard version 1.2.1 (the
most current release).
