TOO BIG
The magnitude of the number is too large to be converted to HEX,
OCT, or BIN base. The number must be in the range
-34,359,738,368 < n < 34,359,738,367.
XEQ OVERFLOW
A running program attempted an eighth nested XEQ label. (Up to
seven subroutines canbe nested.) Since SOLVE and /FN each usea
level, they can also generate this error.
