   I am referencing "The Programmer's PC Sourcebook" by Thom Hogan to try
and read a block from a disk unit.  On page 3-37, there is int21H, which
does just that.  It tells you what to set up before calling the interrupt,
like AH=27H, CX=Number of records to read, etc.  Besides all the registers,
there is something called DTA.  This is where the actual data read will be
upon return from the interrupt.  I searched the book and can't find what
the DTA is.  It is not listed in BIOS.H, or at least I didn't see it.  Oh,
I'm programming in C.  I use the int86() function.
   Forgetting all this, can anyone that knows how to use int27H, AH=27H tell
me where my data will be after the call?

   Also, while I'm here.  How can I turn the cursor on while I'm running
my program?  I have a getch() function waiting for a keypress, and I'd like
the cursor to be on.  Is this possible, or will I have to blink a cursor
myself?  Thanks again!
