Informix Error -4661

-4661 Access control restrictions are not allowed for this intrinsic member

function.

The intrinsic member functions !copy() and !derive() must have PUBLIC access control, which is the default access control for member functions.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4661 fires when an access-control keyword (other than PUBLIC) is applied to !copy() or !derive() — per the official guidance, these intrinsic member functions must have PUBLIC access control, which is already the default for member functions.

An explicit non-PUBLIC access control specifier on !copy() or !derive(), per the official guidance — the direct, only cause.

Solutions / Resolution

Remove the access-control restriction, per the official guidance, or make it explicitly PUBLIC — the same as the default.

Examples

A restricted intrinsic member function

CLASS Order
  PRIVATE !copy()
  -- -4661: !copy() must be PUBLIC
END CLASS

Corrected

CLASS Order
  !copy()
END CLASS

Diagnostic Checks

Check !copy()/!derive() declarations for a non-PUBLIC access-control keyword, and remove it.

An access-control keyword was applied to !copy()/!derive(), which must stay PUBLIC — remove the restriction.
