3278 Apl/Text Feature - IBM 3270 Operator's Manual

3278 APL/Text Feature
The 3278 APL/Text feature, the Extended Character Set Adapter feature (pre-
requisite feature for the APL/Text feature), and the appropriate Typewriter/APL
or Typewriter/Text keyboard enable a 3278 operator to work with either APL or
Text applications as well as with existing applications.
A 3278 that has the APL/Text feature installed can:
• Display the 222-character-plus-space APL/Text character set shown in Figure
4-8, and
• Be used to enter a 175-character-plus-space set of the APL/Text character set
when equipped with the Typewriter/ APL keyboard, or
• Be used to enter a 159-character-plus-space set of the APL/Text character set
when equipped with the Typewriter/Text keyboard
The remainder of this section describes the operations of the Typewriter/ APL and
Typewriter/Text keyboards that are different from the normal Typewriter keyboard.
If you are not familiar with the operation of the Typewriter keyboard, read the
Typewriter Keyboard section in Chapter 3 before continuing with this section.
