We try to keep things on the forum, so they are public knowledge.
I found a small article on the Guardian website, which is available HERE, which was printed over a year ago.
You might want to try the ideas there.
As for the program lococonv, you may like to try these steps.
Note: You didn't say if where using windows or anything, so these instructions are on the basis you do. If not, let me know, and I will help.
Open "My Computer" from the desktop.
If using Windows XP, then from the "Start" menu
Open the C drive.
This is often marked with a name, however, it usualy has "C:" in brackets.
Using the right mouse button, select "New" from the list.
A menu will pop-out from the side, click on "Folder"
It will allow you to edit the name right away, call it "docs" and hit return
Open this folder, which should present a blank screen
Create a second folder, and name it "locodocs"
You now need to do two things.
Copy all your locoscript docs to the folder "locodocs"
Copy the program "lococonv.exe" to the "docs" folder
Click on the "Start" button and goto run
If using XP, type "cmd"
If using Windows 95, 98 or 98SE, type "command"
Now click OK
In the dos box, type "cd c:\docs", hit return
Now type "lococonv locodocs rtfdocs" and hit return
This should convert all the files for you, without harming the existing files.
