Hi Gerald, Yes, I'm the Anthony Hanmer who posted some L-systems a long while ago. Thank you for answering my questions. Actually, of the 4 limitations I mentioned, the ones concerning maximum number of entries in a single .ifs or .ls file are the least important for me. I CAN always split up large files into smaller ones, and this is in fact what I have already done, so no worries. I was more hoping to have the other 2 limits removed - those on LS string length (160 characters) and IFS object number (32). But again, these are not limits which really threaten or even prevent my main work - at the moment. However, if Fractint is moving out of its format into somthing less restricted in the future, I ask that all 4 of these limitations be remembered and removed - IF that is possible. If not, life goes on and it's STILL the best fractal programme around!
