This is true. However, there are some problems. If you want to do a recursive
scan of a directory structure under DOS, you have to save the context in the
DTA before starting a scan of a different directory. This is done by using
the DTA-changing DOS calls, and I assume this is how the MSC _findfirst/next
works. 

There isn't a DTA under OS/2; you create handles to directories and just use
the right one to get the required context. Fine, except that if you use the
OS/2 calls (DosFindFirst/Next), under FAPI you have only one directory
handle and no way to save or restore context. I ended up writing two lots
of code that have no real overlap.
