There must be a way....

Man, all I want out of life is to check the function keys while
I'm executing a repeat...until handler. I want it to work like this:

  put the ticks + 180 into endTick
  repeat until the ticks >= endTick
    if functionKey then
      if functionKey = 1 then doThis
      if functionKey = 2 then doThat
      if functionKey = 3 then doThatOtherThing
    else
      beep
    end if
  end repeat

Now, I know that this is not how to use functionKey, and that what
I probably really want to do is use some kind of XFCN, but given that
this must run with HyperCard 2.0, I'm wondering if there are XFCNs out there
to do this (or does HC 2.0 have this ability and I'm not reading the right
documentation?)

It doesn't seem like simply reading the @#%&! function keys from within
a handler should be so difficult, yet I'm bashing my brains trying to make
it work! Can onyone help?

Thanks,
