We have been using TML Pascal for programming, but have been trouble using
Appletalk with it. Specifically, I have been trouble using the
ATalk/ABPackage resource file. I believe that this is the same file that
comes with MDS, so maybe someone familiar with that can help. The first
problem: one is told by the manual to include the "atpl" resource from
ATalk/ABPackage into your resource file by  writing:

type atpl = GNRL
,128
.R
ATAlk/ABPackage

Also according to the manual, that is all one needs to do (it explicitly
says that you do not have to change to a special system with Appletalk in
it). No mention of .MPP and .ATP drivers is made.

Unfortunately, RMaker complains that ATalk/ABPackage has some kind of bad
format. ResEdit does not complain, but after pasting in the resource (and
doing the MPPOpen call), I get a bomb id = 2.

I did get everything to work by ignoring the ATalk/ABPackage and using the
Install Appletalk program on the software supplement to change a vanilla
sytem to an Appletalk system. I assumed that the installer added the.MPP and
.ATP drivers to the system file (possibly an INIT resource as well, but I
haven't looked recently).

My questions: why did RMkaer complain? Why should ATalk/ABPackage work at
all? What is an atpl resource? Why don't I have to get an .MPP and .ATP
reource from somewhere? Are those drivers hidden in the atpl resource
somewhere? Has anyone gotten Appletalk to work just using whatever TML or
MDS provided>
