This topic discusses display support for inserting shift-control characters. Also discussed are the number of extended characters and input fields that can be displayed, and the effects of displaying double-byte data on alphanumeric workstations.
The system inserts shift-control characters into DBCS-only fields automatically.
To insert shift-control characters into open fields or either fields, follow these steps:
The system inserts a pair of shift-control characters at the same time. 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 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.
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.
The use of DBCS input fields affects the total number of input fields allowed on a display. For a local 5250 display, you can specify as many as 256 input fields. However, each three instances of a DBCS field reduces the maximum number of fields by one. For example, if there are nine DBCS fields on a display, then the maximum is 256 - (9/3) = 253 input fields.
Alphanumeric displays cannot display double-byte data correctly. If you try to display double-byte data at an alphanumeric display, the following happens:
