Headings. You can use the Requester Definition screen to specify how a heading will be
displayed on the application screen. You can modify the text for a heading on the
Display Detail screen, overriding the text specified in the DDL (if any), or you can
specify heading text for the first time on the Display Detail screen.
The Pathmaker product can derive the heading text from either the Enscribe DDL field
name, the NonStop SQL column name, or the HEADING clause. Both the Enscribe
and the NonStop SQL data definition languages include the HEADING clause as part
of their syntax.
The Heading field on the Requester Definition screen tells the Pathmaker product
which text you want to use:
HEAD Uses the heading text optionally specified in the field’s DDL description. If
you did not specify heading text in the DDL definition or on the Display
Detail screen, the Pathmaker product uses the field name.
NAME Uses the actual field name in the DDL description, ignoring any text in the
field’s DDL description.
NULL Shows fields without headings of any kind.
The Display Detail screen shows the heading text (if any) currently associated with the
data field. This screen initially shows the text specified in the field’s DDL HEADING
clause; if no text exists, the screen shows the field name. You can override the text
specified in the DDL HEADING clause or specify heading text for the first time by
using the Display Detail screen.
If you use a slash (/) in your heading text, the default screen generator will do one of
two things:
If the screen is in tabular format, the default screen generator interprets the slash
as a new line mark.
If the screen is in compressed or uncompressed format, the default screen
generator interprets the slash as a blank.
Terminal Type. You can use the Requester Definition screen to specify the type of
terminal on which the requester will run. Terminal type applies to TRNS and MENU
requesters.
Valid terminal types are:
6530 A terminal family manufactured and sold by Tandem. A 6530 requester can
be used on 6526 terminals, 6530 terminals, 6540 terminals, JET 6530, or on
any terminal that can emulate a 6530 terminal.
6520 A terminal model formerly sold by Tandem. A 6520 requester can be used
on any 6520, 6530, or 6540 terminal.
3270 A terminal family manufactured by other companies and used with NonStop
systems, including 3270 Kanji terminals.
The default terminal type is 6520.
