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.
