I have been experimenting much with IFS and L-system types in Fractint - though I'm afraid my findings are not yet ready for release. There are several limitations I have come up against, and I wonder if they might be removed in the next release of Fractint - I think they are all no longer necessary with the general speed and power of computers nowadays: In both IFS and L-system types, a ceiling on the number of entries allowed in their respective files (*.ifs and *.ls) - 2000 and 1000 items respectively, if memory serves; In IFS types, a limit of 32 pieces making a specified IFS; In L-system types, a limit of 160 characters per line. Might these constraints please be removed? Thank you, Tony Hanmer _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail
