Change values in or add fields to array of HeaderFields


fields = replaceFields(fields,FieldName1,FieldValue1,...,FieldNameN,FieldValueN)
fields = replaceFields(fields,newFields)


fields = replaceFields(fields,FieldName1,FieldValue1,...,FieldNameN,FieldValueN) changes the existing fields in each header field with the specified names to the indicated values and returns the updated array. This method is the same as changeFields, but if a field does not exist, then replaceFields adds it to the end of fields.

fields = replaceFields(fields,newFields) changes the existing fields in each header field to the names, values, and types specified in fields. This syntax might change the class of an existing field if the field name is a case-insensitive match to a name in fields.

Input Arguments
