HED FREQUENTLY** ASKED QUESTIONS
(** = at least one time asked, sometimes even two !)
Q. My OS/2 reports: "System cannot find the file EMX". What is this EMX
file ?
A. Hed, as many other freeware & shareware programms, is compiled with the
emx gnu c. You have to get the emx run time libraries in order to run
hed. The emx run time libraries can be downloaded from any OS/2 ftp site
as emxrt.zip in some place under /os2/unix/emx*.
Q. Why is X so slow under Windows ? Why X feature doesn't work in the
Windows version ?
A. There are two thinks to blame ...
1) Windows. The Console API hed uses is too slow in 95 and extremely
slow in NT.
2) Visual C++. Mallocs and frees are so slow it can take seconds to
free all members of a medium sized linked list.
Q. Hed refuses to parse the fixup table of some file. I'm sure this is a
binary file. Why will hed not understand it ?
A. Hed currently supports only LX (linear executables). Some old 16bit
OS/2 programs come with the outdated NE file format. Hed can parse 16bit
programs but they must be LX binaries. If you are sure the binary is a
valid LX and hed does not understand it please contact the author.
Q. Fixups seem to be ok, but the code they point to doesn't make any sence.
A. This is most propably a compressed file. Try uncompressing it first.
Q. What is the meaning of all those FFFFFFFF offsets in the fixup tables ?
A. Fixups that point to the current module do not always corespond to some
actual data in the binary file. For example, an internal reference to an
iterated or a compressed page does not have some offset in the file
associated with it. FFFFFFFF offsets denote this kind of unresolved
internal references.
Q. Can by any change this particular feature I need be included in hed ?
A. Of course it can. Just e-mail the author and ask for it. Nearly half of
hed features were implemented as a result of some user requesting them. Hed
would have never been what it is without your support.
Q. How can I register hed ?
A. E-mail the author. Tell him how much you like hed. Consider your self
registered.
Q. Is hed a hacking tool disquised as a hex editor ?
A. Yes.
