Field Descriptions The following paragraphs describe the fields on the Data Field Partial screen.
Field
Enter the name of a reference object defined in the requester, the qualified name of a
reference field defined in the requester, the leading characters of a name, or blanks.
The Pathmaker product displays information for the reference object that matches or
follows the information you typed in this field.
To see the full structure of a reference object as defined in DDL or NonStop SQL, press
F9 to access the Reference Field Value List screen.
Rules for entering field names are:
The name of an elementary field cannot already be specified on the screen for the
current requester.
The object name must be in the requester's context list.
To put a field with no corresponding requester context on the screen, you can
draw it as a decoration (simple graphical screen element) and replace the
decoration with the actual field name after adding the field to the requester's
context.
If a reference object has more than one repetition, follow the object name with a
subscript to show which repetition the data field refers to. A subscript is an
unsigned number in square brackets ([]). For example, suppose there are 3
repetitions of the record GROUP-REC. The field FIELD in the second repetition of
the record would be written:
GROUP-REC[2].FIELD
Occurs
To specify the layout of a data field with more than one occurrence, enter values in
any of the following four fields:
Columns
Row Offset
Column Separation
To create a data field with more than one occurrence, use the OCCURS clause in the
DDL definition of the reference object.
The Pathmaker product treats a data field with more than one occurrence as a single
data item. Use the approach described in the example that follows to manipulate the
way in which the set of fields that make up a single data item is displayed.
For example, suppose you have a data item, OCCURS-DEF.FIELD-NAME, with four
occurrences. When you use this screen to define the first occurrence, OCCURS-
DEF.FIELD-NAME, you can define the layout of the four OCCURS-DEF.FIELD-
NAME fields.
