[Coco] ShellPlus, may it rest in peace. Was: Nitros9/Scripts question

[L. Curtis Boyle]

If I remember correctly (it was a *long* time ago I worked on 2.2a), the scripts for turning on/off features have to ben changed, because they are basically modpatching the shell code live, and, from adding in new things, those patch locations changed. I thought I had documented them (what they were changed to) at some point; maybe I didn’t?
I know the unreleased Level II upgrade completely changed how the shell worked (version 2.9 seems to ring a bell), where you had the base SHELL, and the link in modules SHELL2 and SHELL3, although I don’t honestly remember how things were divided up. I know it supported shell command history, but using a more difficult to use method then we did on 2.2a (which is like DOS/Windows with the up/down arrows). I think Bill had added a “pre-load the keyboard buffer” SS.SetStat into SCF to support this, which 2.2a uses.

It was expected that users would apply patches to ShellPlus, NitrOS-9 does not include these patches and they likely would attempt to patch the wrong locations.

>> Stephen,
>> Then by all means, Stay Happy!  :)  I reckon I don't know much about what all Shellplus 2.2a can do then.  When you finish the docs, I'd like to get a copy so I can read up on it.  In the meantime, the only option for the default shell in NitrOS-9 v03.03.00 that I know of is -p which I use in the following way.
>> Dsave /dd ! shell -p
>> Which saves the entire current drive to drive /DD which is the boot drive.  I think the -p puts one command line per line on the screen with no blank lines in between if I remember correctly.  If there are other capabilities of Shellplus 2.2a, then I certainly do not know them, yet.  :)  Please keep me posted.
