With much reading and practice I have become a bit familiar with writing autolisp routines. Things I couln't do a year ago are now becoming quite simple. One thing, however I'm having trouble with is using "while" for loops. Can anyone explain the "while" function and how it works, maybe with a couple of examples. I'm especially baffled by how it is used to read down a data list, looking for info. Any help would be appreciated.
