*QUERY.DEF |
Query Definition and Maintenance Program |
The *QUERY.DEF utility program is called by the Help subsystem to create or modify 'standard' query definitions. Standard queries present a series of items from the records of a specified file. The definition utility allows the programmer to define the file name, fields to display and their format.
The query definition must include the following:
|
Query Title |
Title line for the query window. | ||||||
|
Query File |
Name of the keyed file to be presented. | ||||||
|
Query Key No. |
Key number of the keyed file to be used. This will determine the order of the records to be displayed. | ||||||
|
Query Flds |
There can be up to nine fields displayed within a query. Each field must define the field within a record of the file to display, the offset within the field, the length of the field, a format specifier, a return indicator, and title. Valid format specifiers are:
|
All fields with the return indicator set to "Y" are returned to the program, which invoked the Query. Each field is placed into the input queue, one field at a time.
