It does not change the 112 bytes of environment space used in upper memory
by UNIVESA and NWCDEX whether I put it before or after those drivers are
loaded. If I put the SET commands before the drivers are loaded then it does
increase the env used by those two programs. Also with the SETs first,
NWCDEX does not completely load high, it has 7248 bytes plus env loaded low.
The Prompt string does not effevt this. With all of those SETs, the env
increases to over 400 bytes each. I don't recall the exact amount.

Break is always monitoring for the break keystroke. If it did not it would
be useless. Anytime you have some thing monitoring for some action, it has
to take away some CPU time to devote to that monitoring. I probably also
slows down drive transferes. That I can check with a utility that checks
transfere rates ubless the program turns it off for the test.

5x86-133 with 48MB RAM. Runs a lot better than WINDOZE 9x or ME.

I use Star Office for that under either NT or Linux. I don't think they have
made a 16 bit versin of it and it is FREE. I prefer WP 6.1 under DOS anyway
and have Lotus 1-2-3. I can read and export to any of these and many more
with Star Office. I have converted WP format to Word format and did not even
bother to edit anything using Star Office.
