I have a few sort of unrelated IIGS programming questions that I hope
someone will be able to answer for me.  If you include any examples, please
use Pascal or C.  Thanks.

1)  How can you lock/unlock files from a IIGS desktop application?  Destroy()
returns an error if I attempt to use it on a locked file.

2)  What is the format for the createDate, createTime, modDate, and modTime
fields of some of the ProDOS 16 records?

3)  How can I activate the scroll bars in an NDA window?  I'm writing an NDA
that uses scroll bars in its window, and I set up the window the same way I
do it for regular desktop applications, but the scroll bars don't respond
to mouse actions in the NDA window's scroll bars.  Is there something
different to do for NDA windows?

4)  Is there a way to tell the color of the pixel that the mouse cursor is
currently on?  I can't seem to find an appropriate toolbox call.

5)  Does anyone know how much it costs to upgrade (?) from the TML Pascal
stand-alone version to the APW version?  Also, is there a way to contact TML
Systems through the network?

Thanks a lot.
