Hmm... I don't remember this.

Not really: If you have a big, i.e. less than 80% full, hard disk, (as I do)
put the ARP commands in a directory by themselves, say "ac", and put it
in your path. To take out arp, just remove it from your path. It worked for
me during the 1.2->1.3 switch. If you have floppies only, make whole new
boot disks. Didn't take long for me:-^

I don't remeber having trouble with the standard run in c:. With ARP shell
the difference between c:run and ac/run is supposed to be immeterial.

>I've heard rumors that something similar to ARP, only better designed
>(not cramming everything into one library) is on 1.4. 
I am not sure that not cramming everything in one library will save space:
Assuming that 1.4 puts lots of things into shared libraries [note the plural]
I will expect every shareware/commercial programs to use AmigaDOS style 
wildcards and templates for commands (rather than downloading programs from
#?x and ??-dos). Keeping just GADS, FindFirst/FindNext, PreParse/PatternMatch
and the necessary resource management routines used by these from arp.library
is likely to save may be 20% of memory used by arp.library. In fact, if
one is not careful in designing the hierarchy of the libraries one may end
up using more ram than arp.library, even if the seperate libraries are each
about 20-30%.

Incidentatly, are there any estimates on how long it will take for a
significant proportion of Amiga owners (especially 500 owners) to upgrade
to 1.4? After all, I am supposed to be able include the arp.library
with my programs for free. CBM is not likely to allow one to do that with
the new 1.4 libraries. What happens with this scenario?
