OS/2 has two API's, DosFindFirst and DosFindNext. They are both family APIs which means a program compiled with them will run in both DOS and OS/2 mode. To create a Family Application, first compile your program for OS/2 then use the BIND utility on it to allow it to work under DOS.

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. ----------------------------+---------------------------------------------- Bob Eager | University of Kent at Canterbury rde@ukc.ac.uk | +44 227 764000 ext 7589 rde@ibmpcug.co.uk | 100016.2770@compuserve.com | ----------------------------+----------------------------------------------
