This list complete as of version 14.
None of these are necessarily supported in future.
Add one to any debug value to trigger writing benchmark values to
the file "bench". This gets stripped at startup; so all values
used for other purposes are even.
Example: "fractint debug=8088" forces Fractint to think you have an
8088/8086 CPU and ignore all of the tricky 186/286/386-specific stuff.
"Fractint 8089" does the same thing, but also turns on the benchmark
timer.
16 video.asm pretend not a vga
22 lorenz.c force float for 3D perspective
50 fractint.c compare <r>estored files
70 fractint.c set fpu = 0
72 fractint.c don't use fast >= 287 fpu routines
90 fractals.c force "C" mandel & julia code (no calcmand or calmanfp)
90 fractals.c force generic code for fn+fn etc types
90 parser.c force "C" parser code even if FPU >= 387
100 calcmand.asm force use of 'code32bit' logic
200 fractint.c time encoder
322 parserfp.c disable optimizer (FPU >= 387 only)
420 diskvid.c don't use extended/expanded mem (force disk)
420 realdos.c same for screen save (force disk)
420 editpal.c same for screen save (force disk)
420 jiim.c same for screen save (force disk)
422 diskvid.c don't use expanded mem (force extended or disk)
422 realdos.c same for screen save (force extended or disk)
450 fractint.c abort in batch mode if savename exists
470 calcfract.c disable prevention of color 0 for BTM
600 printer.c paintjet, no form feed
602 printer.c paintjet, flip image
7nn miscovl.c set <b> getprec() digits variable to nn
870 fractint.c set fpu to max 87
1010 fractals.c force fp for newton & newtbasin (no mpc math)
1234 fractint.c force larger integer arithmetic bitshift value
2222 line3d.c show amount of extra seg memory used
2224 line3d.c old just-the-dots logic, probably a temporary thing
2870 fractint.c set fpu to max 287 iit off
2872 fractint.c set fpu to max 287 iit on
3000 general.asm '~' goes to color play mode
3002 realdos.c don't show development in heading
3870 fractint.c set fpu to max 387 iit off
3872 fractint.c set fpu to max 387 iit on
4000 miscres.c turn on math error message (off otherwise)
8088 general.asm set cpu = 86, ie dont use 32 bit stuff
8088 fractint.c set cpu = 86, (case in general.asm is redundant?)
9002-9100 fractint.c reduce video_type to (debug-9000)/2 if init was higher
10000 fractint.c display cpu, fpu, and free memory at startup
10000 fractint.c ? (try extra hard for minimal startup memory?)
nonzero value, line3d.c, show "normal vector" errors instead of just fixing
nonzero value, prompts.c, show info if fullscreen_prompt2 array invalid
