Activate System -> Host Device (H:) in Altirra. Select a directory on your computer and you'll be able to work without DOS.
And to check version of your Action! cart image check ? $B000 in the monitor (Ctrl+Shift+M).
Should return something like: 45056,$B000 = 6, $0136 54 310. As far as I know 3.6 is the latest version.
An interesting option is to utilize atari800 emulator to create a "compiler" to be used on the PC.
Kuba Husak came with an interesting idea which I think it worth to "sell to the world" as it's simply neat:
First you have to record your "events" (opening a file, compilation, writing it out to a file, all on H: device accessible from a PC as well):
atari800 -cart Action\!.rom -cart-type 15 -record tmp
and then playback it (in turbo mode to make it as quick as possible):
atari800 -cart Action\!.rom -cart-type 15 -playback tmp -turbo
Of course to edit Atari files on a PC (in comfortable way) it's necessary to convert at least line endings (in both ways from and to ATASCII).
And the filename (as recorded by atari800) will always be the same, so it's good to write a little script which will take care for the filenames.
