The input-control character clauses are available for terminals in conversational mode
to define the specific input-control characters to be used during execution of an
ACCEPT statement. These clauses are described later in this section.
The field-characteristic clauses are available to define the characteristics of screen
fields. These clauses are also described later in this section.
Base Screen
A base screen is a screen that is initially displayed on the terminal and is used to
establish the current screen for each program unit. In contrast to an overlay screen
that is displayed in the overlay area of a base screen, the base screen can be
displayed independently.
screen-name
is the name given to the base screen.
SIZE lines , cols
indicates the size of the screen. The number of lines and columns can each range
from 1 through 255. The size can be no larger than the physical limits of the
terminal screen for base screens.
If this option is omitted, the default is 24 lines, 80 columns.
field-characteristic-clause
is one or more clauses that define default characteristics for all fields subordinate
to the screen unless these characteristics are explicitly overridden for a particular
group or field. The clauses that can appear here are:
FILL WHEN ABSENT
mnemonic-name WHEN BLANK
UPSHIFT WHEN FULL
USER CONVERSION
