Introduction - IBM 3270 Operator's Manual

The Typewriter keyboard resembles a standard typewriter
keyboard in appearance and key layout. I n fact, most of the keys
do the same thing as the keys of the same name on a typewriter
keyboard.
Many different types of organizations will use the Typewriter
keyboard, and each one has unique needs and, possibly, special
character requirements. IBM provides six versions of the Type-
writer keyboard to meet the needs of everyone who uses the
3270 Information Display System.
Differences between the versions are small and they affect
only a few special symbols. All symbols, no matter what
version keyboard you have, are defined on page 34 under the
heading "S,ymbols and Punctuation Marks". The only other
difference in versions is that your keyboard mayor may not
have twelve additional keys, PF1-PF12, located to the right
of the normal typewriter keys. The discussion of these keys
is included on page 42.
The characters that can be displayed consist of 26 uppercase
alphabetic characters, 10 numeric characters, and 26 symbols
and punctuation marks. The keyboard also contains the control
keys that are required to format and enter an input message.
Operation of any of the character keys causes the character
indicated on the key to be displayed on the screen in the
position marked by the cursor.
Keys that have two characters on their faces can display either
of them, depending upon the position of the SH I FT key. The
lower character displays when the character key is pressed and
the keyboard is in the unshifted mode (the SH I FT key not
depressed). To display the upper character, you must hold the
SH I FT key down while pressing the character key or depress and
release the LOCK key before pressing the character key.
