YEARS ago, Ztree was written for ZBasic....It had some major flaws which I corrected. One day I posted it to the AOL site (gone). For awhile it was at an internet site which I can't find now. The level that was posted had the code plus the values of constants that needed to be used for different size variables. ok..... Somehow I seem to have lost my copy and cannot find the code on the net. Does anyone have this? I also seem to have tossed the old Zbasic book that had the old values for the constants even though they were not quite right, at least I could modify them.....I have the modified code but not the values of the constants. Thanks, TJS
