Setting up a unix directory to appear as a D3 file

First the unix directory must exist.
Create it from unix using mkdir /fullpathname
or from TCL in d3 using !mkdir /fullpathname
Next edit the master dictionary so that the d3 system has a view of this file
The item id will be the name of this file as used by d3 and has no reason to be the same as the 'real' directory name on the host OS

Eg. the host directory is /tmp/termwork

ED MD WORKFILE
001 Q
002
003 unix:/tmp/termwork

Once this is done all host OS files placed in this directory will appear as items in the D3 file called WORKFILE
D3 will automatically treat each line of the file as separate attributes. Even though they really use a line feed CHAR(10) or a CR:LF (Carriage return + Line feed) pair
