wnc5g

I'm not sure if I understood You question correctly, but You can compile / decompile more than one file at once through WinC5G.

Open WinC5G (or WinCRC)

1- navigate to the folder that have your files

2 - order it by type, if necessary

3 - select the first file, press Shift key, and select the last one.

4 - righ-click over the selected files and click on Translate function, OR

5 - click on Translate button in the menu bar.

Interesting.

Never saw this PDL Editor on your screenshot.

It's something You are developing?

I will.

Thanks!
