There has been a number of CDFs etc for dealing with finding files etc in DFW.

CDF's are well and good but important functions like this should be dealt  with by DataEase directly.

In 2275 we have included the following DEOS functions.

Parameters [Optional]
- [Start path] where to start to select file. The dialog remembers the last selection, so this parameter usually are left blank.
- [Return type] default is to return folder selected but you can use the following to override this:
