The RANGE field qualifier keyword causes a field to be reported together with its range value.
Format
RANGE field {field.qualifiers} {NO.NULLS}
where
The RANGE field qualifier keyword is placed before the field name to which it applies and causes the query processor to report the value of the field for each record processed and also to report the range value (the difference between the minimum and maximum value) at the end of the report. Used with breakpoints, the RANGE keyword will also report the range value of the field at each breakpoint.
If the field is defined as multivalued, the RANGE keyword operates on each value in turn.
The RANGE keyword operates only on numeric data. Non-numeric values are ignored except that the default behaviour is to treat null items as zero. The NO.NULLS keyword can be used to prevent null values being included in the calculation of the range value.
Example
The sentence
LIST INVOICES RANGE VALUE CUSTOMER.NAME WITH NO AMT.PAID
would produce a display such as that below in which the range value of the VALUE field is included at the end of the report.
LIST INVOICES RANGE VALUE CUSTOMER.NAME WITH NO AMT.PAID Invoice ...Value Customer................... 74529 £1712.43 J McTavish 74273 £95.23 County Newspapers 28137 £26.20 J Higgins 63940 £141.00 R Bryant 74993 £9.29 Write Right Stationery ======== £1703.14 5 records listed.
