USING AN ENABLE APPLICATION
Fields
You can enter characters in this field up to the end of the
dashed line. You do not, however, have to enter enough
characters to fill the dashed line.
For decimal fields, you must enter the integer portion of the
field, the decimal point, and any values that appear to the right
of the decimal point. Consider the following field:
SALARY .00
If you enter data in this field, it could appear as:
SALARY 34.00__
You must include every value that appears to the right of the
decimal point when you enter data in a decimal field.
If a numeric field accepts a sign, that field contains an extra
character position for the sign. Therefore, you can enter one
less digit than the number of dashed lines displayed. Because
you cannot visually distinguish a signed field from an unsigned
field, ask your data administrator if an application displays
signed fields. If the application displays signed fields, you
must include a minus sign when you enter a negative value in such
fields. (When you enter positive values in these fields do not
enter a plus sign; this sign is both unnecessary and illegal).
For alphanumeric or alphabetic fields, you can enter either
uppercase or lowercase letters of the alphabet. If you try to
read existing records with an operation that involves comparison
(READ APPROXIMATE, READ EXACT, or READ GENERIC), follow these
rules:
• If the existing records contain uppercase letters, enter
uppercase letters when you request a comparison operation.
• If the existing records contain lowercase letters, enter
lowercase letters when you request a comparison operation.
Special Fields in Applications That Display Several Boxes
If your application displays several boxes, be aware of special
fields whose values connect a containing box to a nested box.
These join fields appear directly above the nested box. Figure
8-5 shows a screen with several boxes and identifies the join
fields for each containing box.
