Hi!

I am exploring how DOS works, and especially the file-functions. The
problem is that my reference ("The programmer's PC source book" by
Thom Hogan) seems to contain an error, but I am not sure about this.

When I use interrupt 21h fn 11h (find first file with fcb - I know
that fcb's are outdated, but eg. DIR still uses fcbs) the book sais
that the DTA is filled with the drive # and a DIRENTRY structure.

This doesn't seem to be the case, because the first byte of the DTA
after calling fn 11h is 0ffh, which could mean that the DTA is filled
with an extended fcb-structure (opened or unopened?). But I am not sure
about this, also because you also have to supply an unopened fcb (with
ds:dx pointing to it) to this function. 

Does anybody know what the DTA is filled with after a call to int 21h
function 11h?

Thanks in advance for any reply.
