There really isn't one. There used to be a simple one a long time ago, but I forget what happened to it. There was stuff about starting in one forlder, opening from another folder and saving in a third folder, but that was way too much typing, so I just ignored it.
It's a DOS program, so DOS rules apply. I created a work folder and made a batch file that pointed to it. The Command Prompt comes up pointing to one's user folder, so I put a file named Witpload.bat in my C:\Users\Me folder.
Create a folder C:\matrix games\war in the pacific admiral's edition\stuff
Put a copy of witploadae.exe in the folder.
Make a batch file in your user folder that says cd\matrix games\war in the pacific admiral's edition\stuff
Copy whatever scenario (scenario xxx) you want to play with into the C:\.\.\stuff folder
When you launch Command Prompt, just type witpload <ret> ; that puts you in the right place
Then type witploadae /sxxx /e and it will dump scenario xxx things to csv files in the stuff folder
Do all your nasty
Then type witploadae /sxxx /i and it will update scenario xxx things from the edited csv files
Then just move the scenario xxx files back to the game Scen folder.
It's a lot easier if the executable and the scenario files are in the same folder (a lot, lot less typing), and it's a lot easier if the folder is not the game Scen folder (there's so many files in there, already).
Just a suggestion. Ciao. J
