I use the TDE with Pro Mate II all the time.
You need to make a .bat file like this.  My TDE folder is in Program Files
c:\progra files\tde

file name:      cvasm16a.bat
contents:       @echo off
                cvasm16.exe %1 /s

The /s will strip off the usless stuff.

I then use a shortcut in c:\windows\sendto  CVASM

The shortcut
Cmd line:       c:\progra~1\tde\cvasm16a.bat
Working:        c:\progra~1\tde
Run:            Minimized

Check Close on exit.

Now when you are done with your TDE program, open your folder where your
.obj resides.  Highlight it, right mouse click and Send To, choose CVASM.
It's fast and easy.  If you are running the new MPLAB 3.22.02 you will new
to select File and Import to load your code.

Hope this helps.
Take care  -Jim
