Nested GOSUBs...

Hi,
Just wondering why there is a limit of 4 nested GOSUB's in the Stamp?
I've been working on some code, and have got most of the code that is
repeatedly called upon in Subroutines, to save on EEPROM space.
Example - I cut used EEPROM space down from 48% to 43% tonight, but on
running the program it went back to the start of the code after a button was
pressed (an indication that there are too many GOSUB's within GOSUB's).
I counted the number of jumps I had and it came to 5, so I ended up
repeating a small chunk of code in order to make it all work (and lost 1%
EEPROM space - 44%).
Still, I've saved 4% EEPROM space, but the limit of 4 nested GOSUB's is hard
to avoid sometimes... :-\
Also, an idea for future Stamp Editor releases:
How about the Editor automatically making comments a red colour?
Makes it easier to read the code then (bit like the sample codes on my web
site).
cheers,
Ben, Windy Wellington, New Zealand.
