Hopefully this post isn't too off topic.

I'm attempting to write some *.dbf (dBase III/IV, FoxPro, etc. database files)
functions and was wondering if anyone knew why the 8th and 9th bytes (Which
point to the record starting offset/end of the header section) would be
(apparently) correct in some files and not in others. The file versions are all
0xC(dBase IV w/ memo) Yet, two of the three are off by 80 and 161 bytes. The
files are not corrupted (They read fine in MS Excel and other database programs.
Am I missing something? Anyone who has experience with this and can reply,
thanks, or if you know a more appropriate forum, please tell me, the closest I
could come was the clipper forum. I'm using the latest dm compiler, 32 bit dos
program.

I have no idea, but why would you try to code this kind of stuff?

Implementing the extremely small aspects of checking field id's and information
from only two fields with already working databases is such a small bit of work
that it's faster/simpler(less money) to simply write the code myself. Which I
did, only, the header isn't always where it should be...

So, maybe someone who wrote one of the libraries has an answer? ;)

I guess they do. I do have the Sequiter library and it works rather well.

I was about to do the same thing as you and than realized that I am probably
going to
do it soo many times that I better get a library which takes care of the nasty
details
for me.
