DUPKey
Pressing the DUP key displays an overscored asterisk ( * ) when the A,a/A
switch
is
set
to
A,a; when the A,a/A switch
is
set to A, only the asterisk
is
dis-
played. Also,
as
a result, the cursor advances to the first character location
of
the next input field.
The DUP operation
is
intended
to
provide you with a fast method
of
filling in
the information that
is
the same for every document (such
as
the date). The
DUP key causes a special code
to
be sent to the host system which tells the pro-
gram that a duplication operation is needed. The program
you
are working with,
however, determines the use
of
the DUP key. To verify its use, ask the appro-
priate person in your organization about its
use
or refer
to
the appropriate user's
program guide.
FIELD
MARK
Key
Pressing
the
FIELD MARK key displays an overscored semicolon (
-;
) when the
A,a/A switch to set
to
A,a; when the A,a/A switch
is
set
to
A,
only the semi-
colon
is
displayed. The FIELD MARK key
is
used when operating with an
unformatted display to indicate the end
of
a field to the program.
