Oninit® Troubleshooting Guidance

Reasons / Common Causes

-2021 fires when a COLOR attribute in a form specification (or a display attribute in a 4GL program) names something other than one of the eight predefined colors — per the official guidance, colors 0 through 7 are white, yellow, magenta, red, cyan, green, blue, and black, and must be specified by their exact names.

A misspelled or invalid color name, per the official guidance — the direct, only cause.

Solutions / Resolution

Verify the spelling and punctuation of the color name, per the official guidance, against the eight valid names: white, yellow, magenta, red, cyan, green, blue, black.

Examples

A misspelled color name

ATTRIBUTES
