Causes Fractint to read "filename" for parameters. When it finishes, it resumes reading its own command line -- i.e., "FRACTINT MAXITER=250 @MYFILE PASSES=1" is legal. This option is only valid on the DOS command line, as Fractint is not clever enough to deal with multiple indirection.
Like @FILENAME, but reads a named group of parameters from a parameter file. See "Parameter Files and the [@] Command" .
This command allows to specify the directory where Fractint writes temporary files.
This command sets the directory where miscellaneous Fractint files get written, including MAKEMIG.BAT and debugging files.
Causes Fractint to read the named file, which must either have been saved from an earlier Fractint session or be a generic GIF file, and use that as the starting point, bypassing the initial information screens. The filetype is optional and defaults to .GIF. Non-Fractint GIF files are restored as fractal type "plasma". On the DOS command line you may omit FILENAME= and just give the file name.
Fractint uses directories set by various commands, possibly in the SSTOOLS.INI file. Uf you want to try out some files in the current directory, such as a modified copy of FRACTINT.FRM, you won't Fractint to read the copy in your official FRM directory. Setting curdir=yes at the command line will cause Fractint to look in the current directory for requested files first before looking in the default directory set by the other commands. Warning: [tab] screen may not reflect actual file opened in cases where the file was opened in the DOS current directory.
This command invokes a batch facility to copy fractal and color information stored in GIF files to PAR format. The syntax is:
fractint filename.gif makepar=parfile.par/entryname >> makepar.log The entryname is optional and defaults to the name of the gif filename if absent. Other parameters can appear before the makepar= command, but anything after will ignored. If the parfile and entryname exist, the entry will replace the previous entry. If the entry doesn't exist, it will be added. If the parfile doesn't exist it will be created. Redirection of output to a log file is possible in the DOS version because all screen output is written to the standard output.
If you leave the GIF filename out of the command lime but add a map= command, then the makepar command will write a PAR named for the color map with only the colors in the PAR entry. This is a handy tool for converting maps into compressed PAR colors entry. For example, you could type:
fractint map=lyapunov.map makepar=mycolors >> makepar.log This adds a colors-only PAR entry called lyapunov.map to mycolors.par.
This command sets the maximum width of lines in a PAR entry.
Inserts comments into PAR files. These comments can include variables that are expanded at the time the PAR file is created. Variables are indicated by $varname$. Underscore characters are expanded to blanks. If you want to include the special characters '$', '_', or '\' in a comment, precede the character with '\'. Supported variables are:
Variable Expands to Example Variable Expands to Example =============================== =============================== $year$ time:year 1996 $date$ mo. day, yr Aug 17, 1996 $month$ time:month Aug $calctime$ h:m:s 4:34:45.3 $day$ time:day 12 $version$ version 1940 $hour$ time:hour 21 $patch$ patch number 2 $min$ time:minute 34 $xdots$ horiz rez 640 $sec$ time:sec 14 $ydots$ vertical rez 480 $time$ time:h:m:s 21:34:14 $vidkey$ video key SF4
You can leave any of the four comment fields unchanged by leaving that position blank. For example, the command comment=//Created_$date$ inserts the text "Created Aug 17, 1996" into the third comment.
See Batch Mode .
Specifying "play" runs Fractint in playback mode - keystrokes are read from the autokey file (see next parameter) and interpreted as if they're being entered from the keyboard. Specifying "record" runs in recording mode - all keystrokes are recorded in the autokey file. See also Autokey Mode .
Specifies the file name to be used in autokey mode. The default file name is AUTO.KEY.
This parameter is useful if you have an unusual coprocessor chip. If you have a 80287 replacement chip with full 80387 functionality use "FPU=387" to inform Fractint to take advantage of those extra 387 instructions. If you have the IIT fpu, but don't have IIT's 'f4x4int.com' TSR loaded, use "FPU=iit" to force Fractint to use that chip's matrix multiplication routine automatically to speed up 3-D transformations (if you have an IIT fpu and have that TSR loaded, Fractint will auto-detect the presence of the fpu and TSR and use its extra capabilities automatically). Since all IIT chips support 80387 instructions, enabling the IIT code also enables Fractint's use of all 387 instructions. Setting "FPU=noiit" disables Fractint's IIT Auto- detect capability. Warning: multi-tasking operating systems such as Windows and DesQView don't automatically save the IIT chip extra registers, so running two programs at once that both use the IIT's matrix multiply feature but don't use the handshaking provided by that 'f4x4int.com' program, errors will result.
Create Fractint documentation file (for printing or viewing with a text editor) and then return to DOS. Filename defaults to FRACTINT.DOC. There's also a function in Fractint's online help which can be used to produce the documentation file - use "Printing Fractint Documentation" from the main help index.
Fractint maintains a list of parameters of the past 10 images that you generated in the current Fractint session. You can revisit these images using the [h] and [Ctrl-h commands. The maxhistory command allows you to set the number of image parameter sets stored in memory. The tradeoff is between the convenience of storing more images and memory use. Each image in the circular history buffer takes up over 1200 bytes, so the default value of ten images uses up 12,000 bytes of memory. If your memory is very tight, and some memory-intensive Fractint operations are giving "out of memory" messages, you can reduce maxistory to 2 or even zero. Keep in mind that every time you color cycle or change from integer to float or back, another image parameter set is saved, so the default ten images are used up quickly.
