I tried the [WOW!] par with fractint v20 and it does the same thing, the Polynomial Degree won't stay at 100. I wonder how Jim was able to 100?
On my fractal dedicated machine running DOS 6.22 I can raise the degree to 237 without problems. But it defaults back to 16 at 238. I am using the most recent developer's release of Fractint.
Running the latest Developer's version under Windows-98(SE) allows me to adjust it up to 111. Anything above that value reverts back to 16.
The answer to this problem lies in the following lines of code in frasetup.c: if(degree > 16) { if((roots=(_CMPLX *)malloc(degree*sizeof(_CMPLX)))==NULL) { roots = staticroots; degree = 16; } } This indicates that when degree is greater than 16, memory is dynamically allocated for the roots of the newton and newtbasin types. If memory allocation fails, then a value of 16 is used for degree. Since Fractint is a DOS program, the amount of memory available is limited to 640 KB minus any used for TSR programs. Under Windows, it is possible to limit the total amount of memory available to values less than 640 KB with a setting in the shortcut properties. Jonathan
