Hi,

does anyone out there know where the extended file handles of
DOS 3.3 + reside in memory? I.e., I know where I can find the first 20
file handles in the PSP, but need to know where the rest of the
( up to 255) handles are located. The interrupt list mentions an
"open file table" address at offset 36 hex in the PSP; does that point
to a segment where the handles are stored? And if so, how do I know
how long that table is? Is there an equivalent "get handle count" to the
"set handle count" function (int 21 hex, function 67 hex) ?

Any and all help is appreciated... please mail your answers, I'll
summarize to the net if there is enough interest.

Thanx in advance, Martin
