I mentioned earlier that I saw an article in RUN magizine that claimed the save and replace function has been fixed. The following is the relevent portion of the Commodore Clinic section of the July 1984 issue of RUN pp. 120: Q: According to Personal Computing, Commodore says the save and replace function on the 1541 doesn't work. I have been using a 1541 for about six months and have had no problems using this function. Can you clear up this apparent conflict? A: Five years ago, on the first PET 2040 disk drives with DOS 1, save with replace didn't work properly. It subtly corrupted disk files other than the one in use, usually after the user had scratched improperly-closed files instead of gitting rid of them with the disk Validate command. DOS 2 corrected that, and save with replace has worked on all Commodore products since, so far as I know. Old rumors die hard. Before using save with replace, be sure your disk has enough remaining space to hold a spare copy of your program, since that is part of its way of working. Your current copy is not replaced until the new copy has been successfully saved, ensuring no loss of data in case of a disaster midway through the save. To use save with replace, simply precede ... (drivel) If this is incorrect I would appreciate knowing, also if it is incorrect, I suggest that whom-ever knows contact the author of this column and set him straight.

Unfortunatley Commodore may want to say the the inherent problem of the 'save and replace' is only a rumor..but I must differ with them. When I first recieved my C-64 and 1541 about 2 years ago I can speak from experiance of having problems with the option. During a school science fair I demonstarted a learning program that I had writen. The program used the 'save and replace' option to save a high score file... During a mishap (In which someone tripped over the power cord) I went to reload the program and lowe and behold I GOT THE SEQUENTIAL SCORE FILE?!?!? (interesting) I then examined the header again and tried to relaod but no luck. From this I would advise users to avoid that function whenever possible.. slb@BNL
