Yes, fixed point. Note that when the constants in this program are non-zero, the results are not the same as the older versions (or any other program I've seen). To see this use the 't' command, select type 'mandel' and set Z0=.3 and Z1=.5 with any version previous to 10.0 and with 10.0. I have sent Email to several of the authors, but haven't gotten a reply yet. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
