It's a mystery. 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. Jim M.

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. Sincerely, P.N.L. ------------------------------------------------- http://home.att.net/~Paul.N.Lee/PNL_Fractals.html http://www.Nahee.com/Fractals/

On my W98 machine, running under Windows I can get up to 135 OK, then it reverts to 16 at 136. Running in MS DOS mode instead of Windows 136 is OK but it reverts at 137. FWIW. Mike

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

Maybe if you chanj the background priority to 257 and the foreground priority to 509. _______ REM Erastosthenes would kill me for using this method. OPTION BASE 0 DIM prime, g AS INTEGER DIM test, d AS LONG OPEN "primes" FOR OUTPUT AS #1 primes(0) = 2 test = 3 primes(1) = 3 WRITE #1, primes(0), primes(1) FOR g = 1 TO 256 test = test + 2 prime = 1 FOR d = 2 TO test / 2 IF test MOD d = 0 THEN prime = 0 GOTO 50 END IF 50 NEXT d IF prime = 1 THEN WRITE #1, test PRINT test; IF test > 36 THEN SOUND test, 1 END IF ELSE g = g - 1 END IF 100 NEXT g CLOSE #1 END
