NESTED_COMMENTS

Severity: info

A block comment contains another block comment.

Why it matters. Different IEC 61131-3 implementations handle (* outer (* inner *) *) differently, some treat the first *) as the terminator, leaving the rest as code. Even where the implementation is well-defined, the syntax is confusing to readers.

Settings. No check-specific config.

Trigger.

(* outer (* nested *) text *)      (* fires *)

Nested block comment
IEC 61131-3 implementations differ on whether `(* outer (* inner *) *)`
is valid. Replace nested blocks with single-line `//` comments or
join them.

Fix. Replace with // line comments inside the block, or join the blocks into one.
