What is COBOL Numeric Field Validation Tips about?

The document discusses issues with validating numeric fields in COBOL. While condition names (88s) and IF statements can validate a value is within a range, they do not check that the field actually contains numeric data. Non-numeric characters may be treated as numeric. The NUMERIC function should be used in addition to range checks to fully validate numeric fields. An example COBOL program is provided to demonstrate these issues.
