[NTG-context] Setting to help with overflow in Metapost
All,
This code is causing an overflow. Isn't there a setting that will allow bigger
numbers?
I am not looking for more code and/or rescaling code, but a setting that I know
is there that will allow larger numbers.

This patch repairs it. Now \startlocalenvironment[syllabus-s] is
properly entered when the argument matches the product. One more bug
has been ironed out. But the fact that it took so long before it
surfaced is telling, obviously not many people have used this
mechanism since the manual came out!
Thanks for acting so fast.

This took a bit of digging, it appears to be a bug in core-job.tex.
The definition of \setvalue{\e!start\v!localenvironment} ends with:
{\grabuntil{\e!stop\v!localenvironment}\relax}}
but that should be:
{\grabuntil{\e!stop\v!localenvironment}\gobbleoneargument}}

Yes, it only guards against loading the environment file twice. The
name is irrelevant.

There are probably system modes predefined for the products
name etc. I'll leave the question to be answered by Hans.

No, I must be my fault, but even with the above help I cannot get it
working.
As far as I can figure out the value of \currentproduct seems NOT to
guard entry to the body of \startlocalenvironment[syllabus-s].
Although the manual here explicitely mentions "component or product",
I cannot see that happen. Also \localenvironment seems to accept any
file for reading instead of rejecting everything except the current
product/component.
In the code of core-job.tex I read:
% more or less replaced by modes
\setvalue{\e!start\v!localenvironment}[#1]%
Must I conclude from this that localenvironments are more or less
passe? So that I can better avoid them and use modes (after
\enablemode) as discriminating criterium?

My unsterstanding is that you do it like this:

\project syllabus
\localenvironment syllabus-local-setup

\stoptext

\project syllabus
\localenvironment syllabus-local-setup
