- They're 'stored contiguously with the file.' Whatever that means...In the
- FAT system they _are_ in a hidden file - but you knew that, right? :)

-
- Yep. The only thing you have to do is set DPMI_DOS_API to ON instead of
- AUTO. And of course you can give the thing as much memory as you want.
-

-
- The EAUTIL program does just that. Look it up in the command reference for
- info.

-
- There are really nice .inf files included with IBM's development stuff. I
- don't know if they'd allow them to be distributed via FTP, tho...I suppose
- you could buy the CD if you have a CDROM drive available - it's only $15.
-
- >7. Where is the source code for InfoZip's stuff?
-
- Never seen it myself...

- Should work...you do realize that such a beastie couldn't access the files
- OS/2 will have locked while it's running...that means the user would have to
- boot from a floppy.
- As for the interface, you could always hope that Turbo Vision (or even
- better, ObjectWindowsPM) will be included in BC++ for OS/2. Then you could
- make it a real OS/2 program...other than that you could always write the
- thing yourself - you'd probably be granted god status if you did that and
- then released the code... :)
