Time to test it out....

2 questions, 
1) how do I specify that I want function main() to start at page 3C:8000?
 Most everything else can go ... wherever.
2) can I use C000-EFFF if F000-FFFF is used by the monitor and we don't
wish to disturb that memory (because it loads the rest of flash for us)?

We looked at the C chips, but they have NO EEPROM, which is an absolute
must.  We even have a Delete4bytes+Program2bytes functions that write 1+
bytes to EEPROM.

Parmameters are set for each unit after calibration, so they go through
their procedures for the IDE: modify the parameters; hit the compile
button; SrecCvrt; and load it onto the chip.  
My current version (6 months newer than the production version) of the
program uses EEPROM for the parameters.  The user interface is currently
a serial terminal with no floating point to ASCII (toooo much space used
up there), and now I'm working on a LCD menu/button interface. 
Eventually, production may^H^H^Hwill switch over to one of the user
interfaces and the "compile-the-parameters-in" procedure will be changed,
freeing up a copy of the compiler (when the EEs get over their fear of
multi-file project software to start using the current version of the
program instead of their tried-and-tested singular file original,
in-house test version I gave them long ago).

Thand, Edward, for the info.
