Summary: 

[]

I've ported a C program to draw Julia sets (skins of fractal dragons) from
a vax here at U of W to my 1040st.  It uses recursion, and on the vax this
goes about 500 to 3000 levels deep, depending on what values i feed to the
program.  Unfortunately, when i moved it to my ST, it died after about 170
nested recursive calls.  Further experimentation indicated that only about
7800 bytes is available for local variables, parameters, and return addresses
on the stack from megamax C.  The manual claims that if you want more stack
space, you can modify the STACKSIZE constant in \megamax\init.c; I changed it
to 64000 bytes and a few other values, but to no avail.
Help!
Does anyone out there know how to make the stack as big as you want?
It seems to me that some other code internal to megamax didn't realize
i'd changed STACKSIZE from the original 8K, if that's any help.

	Thanks in advance,
		Camille.
