Using WITH statements in combination with function parameters can often lead to errors, since the WITH statement is using the record 'field' instead of the - by the developer intended - function parameter.

In the function below, it would be interesting to have a CodeCop rule to alert to refactor the code by either removing the WITH statement, either by renaming the function parameter 'Code' to 'NewCode' or 'PaymentTermsCode' to improve readibility / avoid future conflicts.

CreatePaymentsTerms(Code : Code[10])
WITH PaymentTerms DO BEGIN
INIT;
Code := Code;
...
END;
