By default, Z Data Tools uses the field names
(from your original copybook or from your dynamic
template) as field headings in SNGL and TABL display
format. You can override this by specifying your own
field headings.
To change the field heading:
Enter the E (edit) line command in the Cmd field
adjacent to the field that you want to rename.
Enter the new field heading in the
Heading field on the Field
Attributes panel.
Press the Exit function key (F3) to save your
change and return to the Field Selection/Edit panel.
Repeat for all field headings you want to
change.
The field heading may determine the width of the
display column. The default output width is the
maximum of the number of characters needed to show
the field heading (or field name, if no heading is
specified), and the number of characters needed to
show the value of the field. The following figures
demonstrate how changing a field heading can change
the display width of the field.
Note: While the width of the Employee-No field
has reduced, the width of the Month column has not
changed. This is because the Month field has a Type
of BI and Length of 4. The maximum value that can be
entered into a field of this type has 9 digits,
therefore, the default output width is 9 characters.
To reduce the width of the Month fields, you would
need to modify the field attributes.
