           DRIVERS.TPU    Unit needed to compile LEASTQ.PAS

   By using DRIVERS.TPU, a stand-alone EXE file, LEASTQ.EXE, is created
that does not need the EGAVGA.BGI file to run. Note that this TPU is
for Turbo Pascal 5.0. It will probably not work with 5.5.

   This program uses the $N+, and $E+ compiler directives. This means
that some special code is linked in to run with high precision IEEE 8
byte reals. If your computer has an 80x87 math coprocessor chip, the
program will detect the chip and use that instead of the linked-in code.
On my 4.77 MHz machine the 8087 chip makes a big difference. Users with
AT class machines may find the speed of this program entirely acceptable
even without a coproccesor chip. If you have Borland Turbo Pascal 5.0
and an 80x87 chip, you can recompile the program LEASTQ.PAS with the $E-
directive to get a smaller EXE file.

     Users who program in Turbo Pascal may wish to add their own functions
to the existing library; in addition to writing code to generate your 
function, you will need to make changes to procedures FUNC, GETFUN, RANGE
and YCALC and add a new element to the type 'Species'.
