Mode(s) Explanation and Examples
Singular / Error
22
DECM
Attempt to use a LU decomposed matrix
for solving a system of equations.
Attempt to invert a matrix when it isn't of
full rank.
Solve / FAILEd
20
DECM
The solver did not converge.
7
PRG
Nested use of solve (SLV and SLVQ), inte-
grate, sum or product is not allowed.
12
All
STOS or RCLS attempt using registers that
would overlap the stack. Will happen with e.g.
SSIZE = 8 and STOS 94.
15
DECM
A statistical calculation was started based on
too few data points, e.g. regression or stan-
dard deviation for < 2 points.
10
All
Keyboard input is too long for the buffer
(should never happen, but who knows).
3
All
An instruction with an undefined op-code oc-
curred (should never happen, but who
knows).
14
Integer,
\PRG
Stack or register content is too big for the
word size set.
4
\
α,
\PRG
Division of a number > 0 (or < 0) by zero.
Divergent sum or product or integral.
Positive (or negative) overflow in DECM
(see
above
).
5
11
PRG
Subroutine nesting exceeds 8 levels.
Any key pressed will erase the error message displayed and execute with the stack contents
present. Thus, the easiest return to the display shown before the error occurred is pressing a
prefix twice.
