Hi Bill,
I've managed to add the SORT command, it works like this: SORT(CTRLGUI_SRC
ASC), CTRLGUI_SRC is a variable containing the list of filenames to be
sorted, you can specify ASC or DESC to specify the sort order.
I've looked into the vc7 generator code but didnt find the place to put the
code so I ended up adding the command which was quite straight forward)
Anyway, I've attached the source if you want to consider adding it
somewhere.
Greetings,
Mike
