The DOS listing is actually a DUP.SYS listing, though - not the FMS routines that actually manage the disk, but the "DOS 2.0" menu- screen application program that lets you REQUEST various disk/file operations... I believe the FMS itself (the REAL "DOS" listing) appears in "Inside Atari DOS," a long-since-discontinued COMPUTE! Books publication. I've been trying for years to track down and obtain a copy, but they're very scarce. COMPUTE! doesn't print it, doesn't have any copies (that they know of or will admit to) lying around unsold, and doesn't have any suggestions on obtaining it; the only option here seems to be to find someone (through this Net or other means) who HAS a copy and would be willing to sell/loan it to you. I know there are a couple of people reading this right now who have it and are willing to sell/give it; I've talked to a few of them, and come "this close" a couple of times, but so far none of the deals have been completed although the current one is JUST ABOUT to! (Hi Tom... mail it yet??? :-) ) Give it a try. Chris -- UUCP: !{iuvax,pur-ee,uunet}!bsu-cs!cfchiesa cfchiesa@bsu-cs.UUCP
