Even simple (?) directory listing programs have to be modified to run... Could someone who has extensive hands-on experience on DOS 4.00 summarize the changes made in it re version 3.30 ? I have been told that the changes are NOT limited to breaking the 32M partition limit, but that they also break lots of software that definitely does not go to the disk drive direct... were all these changes necessary, or is this a case of changes-just-for-the-heck-of-it ?

The reason DDIR doesn't work quite right under DOS 4.00 is that it relied on the first character of a non-file line being a space. Under DOS 4, a directory listing prints the space as the LAST character of the PREVIOUS line (or some dumb thing like that), so that it looks the same but doesn't "capture" the same. I had to patch it with a kludge that looked for lower- case letters in the output generated by DIR, since filenames are always in uppercase but the "Volume ..." and "Directory of ..." lines are not. Another major enhancement (?) to DOS 4 is that they've reworked the File Allocation Table scheme around enough so that early versions of the Norton Utilities (or any utility that bypasses INT 21 for disk I/O) will choke on it. This is to accomodate hard disks larger than 32 Megabytes. Also, the BIOS, operating system, and command interpreter have grown, as have all the standard utilities, so you'll have to rush right out and buy an even BIGGER memory board and hard drive. (Anyone remember when the MORE filter was about 300 bytes long?) -- Jeff Boeing: ...!csun.edu!csuna!abcscagz (formerly tracer@stb.UUCP) ---------------------------------------------------------------------------- "Let's split up -- we can do more damage that way." -- Gh0stbusters
