Use caution.  Myself, unless it is something major, I will not use a 
TSR written in a high level language.  For Turbo Pascal (at least the
last time I used the free-kick source), the program took 64K.

Using assembly, that size can be reduced greatly.  I have a programmer's
calculator with all the bit stuff, four bases, etc that takes 3K.  The same
program written in C took 40K.  (Sorry, I don't have source :))

On these IBMs memory is such prime estate, I am very picky about how I
use mine.
