Hi Folks,
  I've got this slight problem with Turbo Pascal running on the PC-AT. I'm
using Database Toolbox and I've got this weird bug. Sometimes when I change the
contents of my program, but make no changes in the data files, index files, or
toolbox affiliated variables, my program bombs and throws me out to DOS when
I do different operations on the file (open, add, delete, close). I use a
couple of machine language external subroutines, which work perfectly, but
I'm almost positive that I don't stray into any illegal neighborhoods in
memory. When I erase my data and index files and start over, everything works
fine. Any suggestions?
  Also, is there any way to open the serial port on the PC with Turbo Pascal?
  Thanks.
