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
