I have stepped through all labs.
A few questions I have to look at closer.
Here is a list of errors encountered

In BON, the coefficients given in the equations defining the
Bernoulli numbers are the alternating binomials, and are used
as shown below. The function x: (used in coeffs) invokes the
use of extended precision, presenting rationals in the form
1r2 and 1r6, etc.:

Then use Newton's iteration to find a zero of this function.

── (6 of 17) Trapezoid membership function Generation ───────
The dyadic verb "trap" creates trapezoid shaped membership
functions. Each trapezoid is defined by a 4-tuple (aa, bb,
cc, dd). The 4-tuple is the righthand argument for the dyad
trap; the lefthand argument is the vector of universal set
values.
The "core" of a fuzzy membership function are the values
which correspond to a membership value of 1.0. The "support"
of a fuzzy membership function are the values which
correspond to a membership value > 0.0.

── ((1) 1 of 36) 1. Introduction ────────────────────────────
This lab is written as a companion to Seymour Lipshutz
"LINEAR ALGEBRA" of Schaum's Outline Series, published by
McGraw Hill, 1991, ISBN 0-07-038007-4. It will be referred to
here by the author's initials SL.
The use of the computer makes it possible to experiment with
mathematical ideas with ease and precision, sometimes
expanding on the text-book treatment, and often providing new
insights. You are always in control of the computer and may
enter any experiment you wish, concluding each entry by
pressing the Enter key.
Although texts in the Schaum Outline Series are not commonly
adopted for college courses, one of them is chosen here for
the following reasons:
1. Adopted texts in Linear Algebra are so various that
there appear to be none that are widely used.
2. Designed as aids to students in a variety of courses,
the Schaum Outline Series provide broader treatments
than most other texts.

(just a short question)
(from the mapped files)
── (7 of 68) overview (ctd) ─────────────────────────────────
When you start an application the OS creates a new process.
A process has a 4GB virtual address space (VAS); each address
from 0 to 2^32 can have a byte value.
Initially none of the addresses have values.
