UNIQUE DISPLAYABLE CHARACTERS
IBM has two special characters, Duplicate (DUP) and Field Mark (FM). Both provide the
application program with special information that aids data entry.
Depending upon the setting of the (A,a/A) Switch, these characters take one of two forms.
•
When set for Dual Case (A,a) the DUP character appears as an asterisk with an overscore
<*). The FM character appears as a semicolon with an overscore (;-) .
• When
set for Mono Case (A), both characters lose their overscore so that the DUP character
appears as an asterisk (*) and the FM character appears as a semicolon ( ; ).
The Duplicate (DUP) Key
IBM 3276. The DUP operation allows you to duplicate input data that occurs repeatedly.
If the cursor is in an unprotected field when you press the DUP key, the 3276 displays a DUP
character in the field and moves the cursor to the first character position of the next unpro-
tected field.
If the cursor is in a protected field or at an attribute byte when you press the DUP key, the
keyboard locks, and the message (tGo Elsewhere" appears in the Status Line.
HP 2625A. Simultaneously pressing the ALT key and the DUP key implements the function
of
the DUP key. As the HP 2625A doesn't support Mono Case, your terminal displays the DUP
character as an asterisk with an UNDERSCORE (:!:).
The Field Mark (FM) Key
IBM 3276. When the screen contains an unformatted display, you may use the FM key to
show
an application program where a field ends.
If the cursor is in an unprotected field when you press the FM key, the 3276 displays a FM
character at the cursor's position and moves the cursor to the first character position of the
next unprotected field.
If the cursor is in a protected field or at an attribute byte when you press the FM key., the
keyboard locks and the message ((Go Elsewhere" appears in the Status Line.
HP 2625A. Simultaneously pressing the ALT key and the FM key implements the Field Mark
function. As the HP 2625A doesn't support Mono Case, your terminal displays the FM charac-
ter as a semicolon with an UNDERSCORE (i.).
THE DISPLAY
The screen's display contains a fixed number ofhorizontal rows. Depending upon the configu-
ration,
your nscreen" may consist of 24 lines, 32 lines, or 43 lines. Each row contains 80
columns.
