Informix Error -35210: INTERNAL ERROR: feature name not yet implemented.

Reasons / Common Causes

-35210 is a critical internal preprocessor error — per the official guidance, all supported features are implemented, so this message firing at all indicates an internal inconsistency rather than a genuine unimplemented-feature situation.

1. An internal inconsistency in the preprocessor's feature-support tracking, per the official guidance's framing — not a genuinely unimplemented, documented restriction.

Solutions / Resolution

1. If this internal error recurs, note all circumstances and contact IBM Technical Support, per the official guidance — this is the documented, only resolution path.

Examples

N/A

No specific triggering statement is documented — this is a critical internal parser fault.

Diagnostic Checks

1. Record which feature name the message names, per the official guidance, along with the full circumstances, for escalation.

• -35200 — "Fatal parse error; string." Another "contact IBM Technical Support" internal preprocessor fault.
• -35202 — "Too many nested blocks." Same internal-fault family.
• -35208 — "INTERNAL ERROR... case error." Same INTERNAL ERROR-labeled family.
• -35209 — "INTERNAL ERROR: ...assertion error." Same family.

An internal inconsistency, since all supported features are actually implemented — capture the named feature and full circumstances, and escalate to IBM Technical Support if it recurs.
