E-CE0010 — Step of a slice or range is zero

Error Type	Compile Error
Phase	compiling the problem into an OMMX instance
Python exception	`ValueError` (builtin)

Message

The step of a {construct} cannot be zero.

Possible fix: use a non-zero step.

Cause

A slice such as x[a:b:0] or a range such as jm.range(a, b, 0) was evaluated with a step of 0. A zero step would never advance, so it is rejected, matching Python’s own slicing and range rules. The step is checked when the slice or range is evaluated to concrete values during compilation, so a computed step expression triggers this error only when the instance data makes it zero. An omitted slice step defaults to 1 and never triggers this error.

Fix

Use a non-zero step. If the step is a computed expression, ensure it cannot evaluate to zero for any instance data.
