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
100
calcmand.asm
force use of 'code32bit' logic
200
fractint.c time encoder
420
diskvid.c don't use extended/expanded mem (force disk)
420
realdos.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)
600
printer.c paintjet, no form feed
602
printer.c paintjet, flip image
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
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
