Inserting shift-control double-byte characters
The system inserts shift-control characters into DBCS-only fields automatically.
To insert shift-control characters into open fields or either fields, do the following:
1. Position the cursor in the field in which you want to insert double-byte data.
2. Press the Insert Shift Control Character key (according to your DBCS display
station user’s guide).
The system inserts a pair of shift-control characters at the same time, as follows
(where 0E represents the shift-out character and 0F represents the shift-in
character):
0E0F The system leaves the cursor under the shift-in character and puts the keyboard in
insert mode. Insert double-byte characters between the shift-control characters. To
insert double-byte characters, start keying in double-byte characters at the cursor
position. For example, enter the double-byte character string D1D2D3, as follows
(where 0 E represents the shift-out character, 0 F represents the shift-in character, and
D1, D2, and D3 represent three double-byte characters):
0 ED1D2D30 F
To find out if a field already has the shift-control characters, press the Display Shift
Control Character key.
DBCS-graphic fields store double-byte characters without requiring the use of shift
control characters. Shift control characters should not be inserted in graphic fields.
Number of displayed extended double-byte characters
The system can display up to 512 different extended characters on a Japanese
display at one time. Additional extended characters are displayed as undefined
characters. However, the additional extended characters are stored correctly in the
system.
Number of DBCS input fields on a display
The use of DBCS input fields affects the total number of input fields allowed on a
display. For a local 5250 display station, you can specify as many as 256 input
fields. However, each three instances of a DBCS field reduces the maximum
