JUSTIFY/NO JUSTIFY ATTRIBUTE. For those types of
fields which do not include automatic field editing (all
characters, alphabetic, auto-upshift, alphanumeric, in-
teger, signed deciinal, and numeric), you may select the
"JUST I FY" attribute which causes any data within the field
to be automatically justified whenever the cursor leaves
the field. Like the optional/required attribute, this at-
tribute is specified by way
of
the field definition menu. For
all characters, alphabetic, auto-upshift, and alphanumeric
fields, the data is left-justified. For integer, signed decimal,
and numeric fields, the data is right-justified. The jus-
tify/nojustify attribute is ignored for implied decimal, con-
stant, integer fill, signed decimal fill, and implied decimal
fill fields.
TOTAL FILUNO TOTAL FILL ATTRIBUTE. For
any
type of field (except, of course, constant fields) you m.a,y
specify "TOTAL FILL" attribute. This attribute signifies
that, if any character position within the field contains a
valid character, then every character position within the
field must contain a valid character. Like the
optional/required and justify/no justify attributes, this at-
tribute is specified by way of the field definition menu. The
"TOTAL FILL" attribute is checked as the cursor is about to
leave the field. If"TOTAL FILL" is in effect and all character
positions of the field do not contain valid characters, then
the keyboard is "locked", the bell is sounded, the cursor
moves to tp.e start of the field, and an error message ap-
pears at the bottom of the screen. To correct the situation,
press _
and then enter the data item in a manner which
ensures that all character positions contain a valid char-
acter (right justify it and include leading zeros, for
example, for the numeric field types).
Designing and Using Forms
Defining Fields From the Keyboard
From the keyboard, you specify the desired field type and
explicit attributes using a menu which you access using
the following keystroke sequence:

Figure 5-6 illustrates the field definition menu. While the
menu is displayed on the screen, the terminal is implicitly
in format mode. The menu contains four unprotected fields
that you access using the _
and _
keys. While the
cursor is positioned in any of these fields, you select the
desired parameters by using the "NEXT CHO I CE" ( . . ) and
"PREVIOUS CHOICE" ( . . ) function keys. The" func-
tion key resets the fields in the menu to their default
values.
When you have selected the desired field type and explicit
attributes, you then save them by pressing the
"!lave
edi h" ( _ )
function key. When you do this, the menu
disappears from the screen and the function key labels
change back to the
"def

set, as follows:
