Congrats Mel!

Yikes!  A user on the beta team found this error actually, but quite
recently.  It may not be in the conversion docs.  I highly reccomend
changing DIM RECORDS to BEGIN RECORDs and changing DIMs from x.something
to x As Something when dealing with records.  It makes a big difference.

Its not your code itself, but the runtimes.  The runtimes are a lot bigger
than 45k now.  You can manually edit the FB II Rntm file and remove a
couple of INCLUDE statements to cut out stuff you don't use.  As has been
said, keep a clean copy! (Best case here is to copy it into your project
folder, FB will use the one in there before checking the headers folder)

I could sweaar TruncString is a toolbox call??  If possible, ditch your
register statements from the assembler.  Its a lot slower than it used to
be. (in fact, register is on its way out sooner or later)

So

register(a1) = ptr&   to  `   move.l   ptr&,a1

That's right, no more ^ needed by variable names, although it won't hurt
anything.

I noticed about 30k or so of small resources like a SICN and a TEXT
resource you can toss. YMMV

No idea.

They are slated for another release than release 0.  Its too early yet.
Believe me its not gone for good.

Andy had a list of the barest functions but FB would be pretty helpless
without the runtime statements.  You can try remarking out INCLUDE "Subs
DEF.incl" and "Subs USR.incl" if you don't use any DEF or USR functions.

> Or do you just need the library references?

Trust me, you really need those.

> Whats the difference between the lite, regular or fat free run time?

The lite runtime is missing all the GUI statements such as BUTTON, EDIT
FIELD and WINDOW.  It is the equivalent of the SIOUX shell in CodeWarrior.
The FB II Rntm (regular?) is a made from scratch runtime that is meant to
be compatible with FB2's.  The other ones are not complete yet......you
could with a bit of effort make a brand new one altogether.  I would leave
that to Staz and Andy though.

The file Toolbox Standard.incl in the headers folder contains the majority
of what's defined.  I think don't a cross referenced list exists though.

Andy's 'loader' mechanism is what is in the datafork.  The program itself
get stuffed into the FCOD resource.  I don't see how this would be a
problem unless the code compiled to a large size such as 16 megs, which
would mess up the resource manager...but the ppc instruction set can't
handle a program any bigger anyhow.

Check the folder called 'runtimes'.  The shell applications contain all
the resources that are installed by default when your program is built.

New one to me?

Like Jim said, FBII knowledge is what will mess you up....you just keep
wanting to do things because that's how FB2 always wanted it and it takes
a while for it to set in that *it just doesn't work that way anymore*.

Once you do a conversion or two successfully, it will become second
nature.
