Informix Error -8015: An open comment symbol, {, was found inside an already open comment on line line-number, character char-number. This could be due to a failure to closethe previously opened comment, which was begun on line lnum, character cnum.

Reasons / Common Causes

-8015 fires when a { comment-open symbol appears inside an already-open comment — per the official guidance, comments can't be nested.

1. A nested { comment-open symbol, per the official guidance — the direct, only cause — often because the previously opened comment was never closed.

Solutions / Resolution

1. Insert a close-comment symbol where appropriate in the report specification, per the official guidance.

Examples

A nested comment

{ Outer comment { nested comment } still inside outer }
-- -8015: comments cannot be nested

Diagnostic Checks

1. Trace back to the comment opened at the reported lnum/cnum, and close it before the nested { symbol.
