Creating Requesters
for Kanji Terminals
You can use the Pathmaker product to create applications for Kanji terminals. A
Pathmaker application can be run on any Kanji device supported by Pathway
including:
JET 6530 terminals
Kanji PCs that can run PCT-J
Fujitsu F9450 terminals or the IBM 5550 family of terminals
All of these devices have mode keys that allow end users to enter ASCII characters,
Kanji characters, or Katakana characters. These different kinds of characters can be
intermixed.
The method that Tandem products use for representing Kanji characters is known as
SHIFT-JIS. Because terminals can use a variety of Kanji character sets, the Pathway
TCP has the ability to translate between SHIFT-JIS and the Kanji supported on a
particular terminal using a translation library.
Defining Data for a Kanji
Application
In addition to the DDL data types used to define data for other Pathmaker
applications, you can use the PIC N data type to indicate fields that can contain only
Kanji characters.
The PIC N data type is supported in SCREEN COBOL, COBOL85, and DDL. The
Pathmaker product will designate the default screen picture as PIC N for data items
defined through DDL as PIC N. PIC N fields can accept only Kanji characters.
The Pathmaker product will designate the default screen picture as PIC X for data
items defined through DDL as PIC X. PIC X fields can accept a mixture of Kanji and
other characters.
Developing a Kanji
Application
The following points apply to using the Pathmaker product to develop Kanji
applications:
Use a JET 6530 terminal or a Japanese MS-DOS PC that uses 6530 emulation
software (PCT-J) to run the Pathmaker full screen interface.
Check that the appropriate translation library is present in the system library on
the Pathmaker development system.
On the Requester Definition screen, specify the terminal type of each requester in
the generated application as 6530 for JET 6530 terminals and as 3270 for PCs that
run PCT-J, Fujitsu F9450 terminals, or the IBM 5550 family of terminals.
In the Pathmaker full screen interface, you can enter Kanji/Katakana characters in
any textual field (for example, requester title, help text, or function key prompts).
You cannot use Kanji/Katakana characters as identifier names. (For example,
requester names or service names.)
You cannot change the default screen picture for a PIC N data field on the Display
Detail screen to one that mixes PIC N and other picture types.
