I've been experimenting with Deep Zooms using batch files produced by Batcher211, FA100, and FAE210b. Basically they are very simlar to partobat in the manner that they create nested bat files using fractint. The problem that I have encountered is the 128 charater length limit on the DOS command line. Using all these parameters and long high-number addresses often exceeds the Dos 128 character lenght limit and gets "truncated", resulting in a mangled fractal. The trick is to "call" up other nested bat files, *.par files, or possibly sstools.ini files where all those addresses, parameters, and data can be "stored" and not crash the 128 character limit Can you put the parameters, addresses and other info in the sstools.ini file, and then rename the "sstools.ini" file to "5sp.ini" and run it as part of your BAT file? What parameters can go into the sstools.ini file? If that is possible, what would be the correct command line syntax for such an approach? Would it go something like "fractint 5sp.ini........"? I am asking about any approaches that would free up as much of that command line space as possible. When you start doing really deep zooms, just the the addresses get longer and longer, so any additional parameters simply take up space. I have some questions about distributed batch porcessing, ie. a batch file "calling" other batch files. What are the limitations for that aspect of using bat files that might affect the "accuarcy" of the processing? Are there any "memory" or command line length limitations? Is there a limit to how many "CALL" type nested bat files that can be run from one "master" bat file?.Are there any limitations as to how many levels down you can go? All the best, Tony Parker
